     * Implementation Notes for non-IE browsers
     * ----------------------------------------
     * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
     * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
     * URL will be resolved into an absolute URL in the context of the application document.
     * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
     * properties are all populated to reflect the normalized URL.  This approach has wide
     * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
     * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
     *
     * Implementation Notes for IE
     * ---------------------------
     * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
     * browsers.  However, the parsed components will not be set if the URL assigned did not specify
     * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
     * work around that by performing the parsing in a 2nd step by taking a previously normalized
     * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
     * properties such as protocol, hostname, port, etc.

/**
 * @ngdoc module
 * @name ngMessages
 * @description
 *
 * The `ngMessages` module provides enhanced support for displaying messages within templates
 * (typically within forms or when rendering message objects that return key/value data).
 * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
 * show and hide error messages specific to the state of an input field, the `ngMessages` and
 * `ngMessage` directives are designed to handle the complexity, inheritance and priority
 * sequencing based on the order of how the messages are defined in the template.
 *
 * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
 * `ngMessage` and `ngMessageExp` directives.
 *
 * ## Usage
 * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
 * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
 * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
 * {@link ngModel ngModel} directive.
 *
 * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
 * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
 * the `ngMessages` directive.
 *
 * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
 * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
 * directive.
 *
 * The `myField` field is a required input of type `email` with a maximum length of 15 characters.
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Enter text:
 *     <input type="email" ng-model="field" name="myField" required maxlength="15" />
 *   </label>
 *   <div ng-messages="myForm.myField.$error" role="alert">
 *     <div ng-message="required">Please enter a value for this field.</div>
 *     <div ng-message="email">This field must be a valid email address.</div>
 *     <div ng-message="maxlength">This field can be at most 15 characters long.</div>
 *   </div>
 * </form>
 * ```
 *
 * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
 * set to the `$error` object owned by the `myField` input in our `myForm` form.
 *
 * Within this element we then create separate elements for each of the possible errors that `myField` could have.
 * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
 * setting `ng-message="required"` specifies that this particular element should be displayed when there
 * is no value present for the required field `myField` (because the key `required` will be `true` in the object
 * `myForm.myField.$error`).
 *
 * ### Message order
 *
 * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
 * than one message (or error) key is currently true, then which message is shown is determined by the order of messages
 * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
 * to prioritize messages using custom JavaScript code.
 *
 * Given the following error object for our example (which informs us that the field `myField` currently has both the
 * `required` and `email` errors):
 *
 * ```javascript
 * <!-- keep in mind that ngModel automatically sets these error flags -->
 * myField.$error = { required : true, email: true, maxlength: false };
 * ```
 * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
 * Once the user types a single character, the `required` message will disappear (since the field now has a value)
 * but the `email` message will be visible because it is still applicable.
 *
 * ### Displaying multiple messages at the same time
 *
 * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
 * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
 *
 * ```html
 * <!-- attribute-style usage -->
 * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
 *
 * <!-- element-style usage -->
 * <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
 * ```
 *
 * ## Reusing and Overriding Messages
 * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
 * template. This allows for generic collection of messages to be reused across multiple parts of an
 * application.
 *
 * ```html
 * <script type="text/ng-template" id="error-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <div ng-messages="myForm.myField.$error" role="alert">
 *   <div ng-messages-include="error-messages"></div>
 * </div>
 * ```
 *
 * However, including generic messages may not be useful enough to match all input fields, therefore,
 * `ngMessages` provides the ability to override messages defined in the remote template by redefining
 * them within the directive container.
 *
 * ```html
 * <!-- a generic template of error messages known as "my-custom-messages" -->
 * <script type="text/ng-template" id="my-custom-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 *
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            id="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <!-- any ng-message elements that appear BEFORE the ng-messages-include will
 *        override the messages present in the ng-messages-include template -->
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <!-- this required message has overridden the template message -->
 *     <div ng-message="required">You did not enter your email address</div>
 *
 *     <!-- this is a brand new message and will appear last in the prioritization -->
 *     <div ng-message="email">Your email address is invalid</div>
 *
 *     <!-- and here are the generic error messages -->
 *     <div ng-messages-include="my-custom-messages"></div>
 *   </div>
 * </form>
 * ```
 *
 * In the example HTML code above the message that is set on required will override the corresponding
 * required message defined within the remote template. Therefore, with particular input fields (such
 * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
 * while more generic messages can be used to handle other, more general input errors.
 *
 * ## Dynamic Messaging
 * ngMessages also supports using expressions to dynamically change key values. Using arrays and
 * repeaters to list messages is also supported. This means that the code below will be able to
 * fully adapt itself and display the appropriate message when any of the expression data changes:
 *
 * ```html
 * <form name="myForm">
 *   <label>
 *     Email address
 *     <input type="email"
 *            name="myEmail"
 *            ng-model="email"
 *            minlength="5"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message="required">You did not enter your email address</div>
 *     <div ng-repeat="errorMessage in errorMessages">
 *       <!-- use ng-message-exp for a message whose key is given by an expression -->
 *       <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
 *     </div>
 *   </div>
 * </form>
 * ```
 *
 * The `errorMessage.type` expression can be a string value or it can be an array so
 * that multiple errors can be associated with a single error message:
 *
 * ```html
 *   <label>
 *     Email address
 *     <input type="email"
 *            ng-model="data.email"
 *            name="myEmail"
 *            ng-minlength="5"
 *            ng-maxlength="100"
 *            required />
 *   </label>
 *   <div ng-messages="myForm.myEmail.$error" role="alert">
 *     <div ng-message-exp="'required'">You did not enter your email address</div>
 *     <div ng-message-exp="['minlength', 'maxlength']">
 *       Your email must be between 5 and 100 characters long
 *     </div>
 *   </div>
 * ```
 *
 * Feel free to use other structural directives such as ng-if and ng-switch to further control
 * what messages are active and when. Be careful, if you place ng-message on the same element
 * as these structural directives, Angular may not be able to determine if a message is active
 * or not. Therefore it is best to place the ng-message on a child element of the structural
 * directive.
 *
 * ```html
 * <div ng-messages="myForm.myEmail.$error" role="alert">
 *   <div ng-if="showRequiredError">
 *     <div ng-message="required">Please enter something</div>
 *   </div>
 * </div>
 * ```
 *
 * ## Animations
 * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
 * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
 * the DOM by the `ngMessages` directive.
 *
 * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
 * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
 * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
 * hook into the animations whenever these classes are added/removed.
 *
 * Let's say that our HTML code for our messages container looks like so:
 *
 * ```html
 * <div ng-messages="myMessages" class="my-messages" role="alert">
 *   <div ng-message="alert" class="some-message">...</div>
 *   <div ng-message="fail" class="some-message">...</div>
 * </div>
 * ```
 *
 * Then the CSS animation code for the message container looks like so:
 *
 * ```css
 * .my-messages {
 *   transition:1s linear all;
 * }
 * .my-messages.ng-active {
 *   // messages are visible
 * }
 * .my-messages.ng-inactive {
 *   // messages are hidden
 * }
 * ```
 *
 * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
 * and leave animation is triggered for each particular element bound to the `ngMessage` directive.
 *
 * Therefore, the CSS code for the inner messages looks like so:
 *
 * ```css
 * .some-message {
 *   transition:1s linear all;
 * }
 *
 * .some-message.ng-enter {}
 * .some-message.ng-enter.ng-enter-active {}
 *
 * .some-message.ng-leave {}
 * .some-message.ng-leave.ng-leave-active {}
 * ```

   * `ngMessages` is a directive that is designed to show and hide messages based on the state
   * of a key/value object that it listens on. The directive itself complements error message
   * reporting with the `ngModel` $error object (which stores a key/value state of validation errors).
   *
   * `ngMessages` manages the state of internal messages within its container element. The internal
   * messages use the `ngMessage` directive and will be inserted/removed from the page depending
   * on if they're present within the key/value object. By default, only one message will be displayed
   * at a time and this depends on the prioritization of the messages within the template. (This can
   * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
   *
   * A remote template can also be used to promote message reusability and messages can also be

/**
 * @ngdoc service
 * @name $resource
 * @requires $http
 * @requires ng.$log
 * @requires $q
 * @requires ng.$timeout
 *
 * @description
 * A factory which creates a resource object that lets you interact with
 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
 *
 * The returned resource object has action methods which provide high-level behaviors without
 * the need to interact with the low level {@link ng.$http $http} service.
 *
 * Requires the {@link ngResource `ngResource`} module to be installed.
 *
 * By default, trailing slashes will be stripped from the calculated URLs,
 * which can pose problems with server backends that do not expect that
 * behavior.  This can be disabled by configuring the `$resourceProvider` like
 * this:
 *
 * ```js
     app.config(['$resourceProvider', function($resourceProvider) {
       // Don't strip trailing slashes from calculated URLs
       $resourceProvider.defaults.stripTrailingSlashes = false;
     }]);
 * ```
 *
 * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
 *   `/user/:username`. If you are using a URL with a port number (e.g.
 *   `http://example.com:8080/api`), it will be respected.
 *
 *   If you are using a url with a suffix, just add the suffix, like this:
 *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
 *   or even `$resource('http://example.com/resource/:resource_id.:format')`
 *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
 *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
 *   can escape it with `/\.`.
 *
 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
 *   `actions` methods. If a parameter value is a function, it will be called every time
 *   a param value needs to be obtained for a request (unless the param was overridden). The function
 *   will be passed the current data value as an argument.
 *
 *   Each key value in the parameter object is first bound to url template if present and then any
 *   excess keys are appended to the url search query after the `?`.
 *
 *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
 *   URL `/path/greet?salutation=Hello`.
 *
 *   If the parameter value is prefixed with `@`, then the value for that parameter will be
 *   extracted from the corresponding property on the `data` object (provided when calling actions
 *   with a request body).
 *   For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
 *   `someParam` will be `data.someProp`.
 *   Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
 *   method that does not accept a request body)
 *
 * @param {Object.<Object>=} actions Hash with declaration of custom actions that will be available
 *   in addition to the default set of resource actions (see below). If a custom action has the same
 *   key as a default action (e.g. `save`), then the default action will be *overwritten*, and not
 *   extended.
 *
 *   The declaration should be created in the format of {@link ng.$http#usage $http.config}:
 *
 *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
 *        action2: {method:?, params:?, isArray:?, headers:?, ...},
 *        ...}
 *
 *   Where:
 *
 *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
 *     your resource object.
 *   - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
 *     `DELETE`, `JSONP`, etc).
 *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
 *     the parameter value is a function, it will be called every time when a param value needs to
 *     be obtained for a request (unless the param was overridden). The function will be passed the
 *     current data value as an argument.
 *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
 *     like for the resource-level urls.
 *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
 *     see `returns` section.
 *   - **`transformRequest`** –
 *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
 *     transform function or an array of such functions. The transform function takes the http
 *     request body and headers and returns its transformed (typically serialized) version.
 *     By default, transformRequest will contain one function that checks if the request data is
 *     an object and serializes it using `angular.toJson`. To prevent this behavior, set
 *     `transformRequest` to an empty array: `transformRequest: []`
 *   - **`transformResponse`** –
 *     `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
 *     transform function or an array of such functions. The transform function takes the http
 *     response body, headers and status and returns its transformed (typically deserialized)
 *     version.
 *     By default, transformResponse will contain one function that checks if the response looks
 *     like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
 *     set `transformResponse` to an empty array: `transformResponse: []`
 *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
 *     GET request, otherwise if a cache instance built with
 *     {@link ng.$cacheFactory $cacheFactory} is supplied, this cache will be used for
 *     caching.
 *   - **`timeout`** – `{number}` – timeout in milliseconds.<br />
 *     **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
 *     **not** supported in $resource, because the same value would be used for multiple requests.
 *     If you are looking for a way to cancel requests, you should use the `cancellable` option.
 *   - **`cancellable`** – `{boolean}` – if set to true, the request made by a "non-instance" call
 *     will be cancelled (if not already completed) by calling `$cancelRequest()` on the call's
 *     return value. Calling `$cancelRequest()` for a non-cancellable or an already
 *     completed/cancelled request will have no effect.<br />
 *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
 *     XHR object. See
 *     [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
 *     for more information.
 *   - **`responseType`** - `{string}` - see
 *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
 *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
 *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
 *     with `http response` object. See {@link ng.$http $http interceptors}. In addition, the
 *     resource instance or array object is accessible by the `resource` property of the
 *     `http response` object.
 *     Keep in mind that the associated promise will be resolved with the value returned by the
 *     response interceptor, if one is specified. The default response interceptor returns
 *     `response.resource` (i.e. the resource instance or array).
 *   - **`hasBody`** - `{boolean}` - allows to specify if a request body should be included or not.
 *     If not specified only POST, PUT and PATCH requests will have a body.
 *
 * @param {Object} options Hash with custom settings that should extend the
 *   default `$resourceProvider` behavior.  The supported options are:
 *
 *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
 *   slashes from any calculated URL will be stripped. (Defaults to true.)
 *   - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
 *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
 *   This can be overwritten per action. (Defaults to false.)
 *
 * @returns {Object} A resource "class" object with methods for the default set of resource actions
 *   optionally extended with custom `actions`. The default set contains these actions:
 *   ```js
 *   { 'get':    {method:'GET'},
 *     'save':   {method:'POST'},
 *     'query':  {method:'GET', isArray:true},
 *     'remove': {method:'DELETE'},
 *     'delete': {method:'DELETE'} };
 *   ```
 *
 *   Calling these methods invoke an {@link ng.$http} with the specified http method,
 *   destination and parameters. When the data is returned from the server then the object is an
 *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
 *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
 *   read, update, delete) on server-side data like this:
 *   ```js
 *   var User = $resource('/user/:userId', {userId:'@id'});
 *   var user = User.get({userId:123}, function() {
 *     user.abc = true;
 *     user.$save();
 *   });
 *   ```
 *
 *   It is important to realize that invoking a $resource object method immediately returns an
 *   empty reference (object or array depending on `isArray`). Once the data is returned from the
 *   server the existing reference is populated with the actual data. This is a useful trick since
 *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
 *   object results in no rendering, once the data arrives from the server then the object is
 *   populated with the data and the view automatically re-renders itself showing the new data. This
 *   means that in most cases one never has to write a callback function for the action methods.
 *
 *   The action methods on the class object or instance object can be invoked with the following
 *   parameters:
 *
 *   - "class" actions without a body: `Resource.action([parameters], [success], [error])`
 *   - "class" actions with a body: `Resource.action([parameters], postData, [success], [error])`
 *   - instance actions: `instance.$action([parameters], [success], [error])`
 *
 *
 *   When calling instance methods, the instance itself is used as the request body (if the action
 *   should have a body). By default, only actions using `POST`, `PUT` or `PATCH` have request
 *   bodies, but you can use the `hasBody` configuration option to specify whether an action
 *   should have a body or not (regardless of its HTTP method).
 *
 *
 *   Success callback is called with (value (Object|Array), responseHeaders (Function),
 *   status (number), statusText (string)) arguments, where the value is the populated resource
 *   instance or collection object. The error callback is called with (httpResponse) argument.
 *
 *   Class actions return empty instance (with additional properties below).
 *   Instance actions return promise of the action.
 *
 *   The Resource instances and collections have these additional properties:
 *
 *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
 *     instance or collection.
 *
 *     On success, the promise is resolved with the same resource instance or collection object,
 *     updated with data from server. This makes it easy to use in
 *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
 *     rendering until the resource(s) are loaded.
 *
 *     On failure, the promise is rejected with the {@link ng.$http http response} object.
 *
 *     If an interceptor object was provided, the promise will instead be resolved with the value
 *     returned by the interceptor.
 *
 *   - `$resolved`: `true` after first server interaction is completed (either with success or
 *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
 *      data-binding.
 *
 *   The Resource instances and collections have these additional methods:
 *
 *   - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
 *      collection, calling this method will abort the request.
 *
 *   The Resource instances have these additional methods:
 *
 *   - `toJSON`: It returns a simple object without any of the extra properties added as part of
 *     the Resource API. This object can be serialized through {@link angular.toJson} safely
 *     without attaching Angular-specific fields. Notice that `JSON.stringify` (and
 *     `angular.toJson`) automatically use this method when serializing a Resource instance
 *     (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON%28%29_behavior)).
 *
 * @example
 *
 * ### Credit card resource
 *
 * ```js
     // Define CreditCard class
     var CreditCard = $resource('/user/:userId/card/:cardId',
      {userId:123, cardId:'@id'}, {
       charge: {method:'POST', params:{charge:true}}
      });

     // We can retrieve a collection from the server
     var cards = CreditCard.query(function() {
       // GET: /user/123/card
       // server returns: [ {id:456, number:'1234', name:'Smith'} ];

       var card = cards[0];
       // each item is an instance of CreditCard
       expect(card instanceof CreditCard).toEqual(true);
       card.name = "J. Smith";
       // non GET methods are mapped onto the instances
       card.$save();
       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
       // server returns: {id:456, number:'1234', name: 'J. Smith'};

       // our custom method is mapped as well.
       card.$charge({amount:9.99});
       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
     });

     // we can create an instance as well
     var newCard = new CreditCard({number:'0123'});
     newCard.name = "Mike Smith";
     newCard.$save();
     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
     // server returns: {id:789, number:'0123', name: 'Mike Smith'};
     expect(newCard.id).toEqual(789);
 * ```
 *
 * The object returned from this function execution is a resource "class" which has "static" method
 * for each action in the definition.
 *
 * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
 * `headers`.
 *
 * @example
 *
 * ### User resource
 *
 * When the data is returned from the server then the object is an instance of the resource type and
 * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
 * operations (create, read, update, delete) on server-side data.

   ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(user) {
       user.abc = true;
       user.$save();
     });
   ```
 *
 * It's worth noting that the success callback for `get`, `query` and other methods gets passed
 * in the response that came from the server as well as $http header getter function, so one
 * could rewrite the above example and get access to http headers as:
 *
   ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(user, getResponseHeaders){
       user.abc = true;
       user.$save(function(user, putResponseHeaders) {
         //user => saved user object
         //putResponseHeaders => $http header getter
       });
     });
   ```
 *
 * You can also access the raw `$http` promise via the `$promise` property on the object returned
 *
   ```
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123})
         .$promise.then(function(user) {
           $scope.user = user;
         });
   ```
 *
 * @example
 *
 * ### Creating a custom 'PUT' request
 *
 * In this example we create a custom method on our resource to make a PUT request
 * ```js
 *    var app = angular.module('app', ['ngResource', 'ngRoute']);
 *
 *    // Some APIs expect a PUT request in the format URL/object/ID
 *    // Here we are creating an 'update' method
 *    app.factory('Notes', ['$resource', function($resource) {
 *    return $resource('/notes/:id', null,
 *        {
 *            'update': { method:'PUT' }
 *        });
 *    }]);
 *
 *    // In our controller we get the ID from the URL using ngRoute and $routeParams
 *    // We pass in $routeParams and our Notes factory along with $scope
 *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
                                      function($scope, $routeParams, Notes) {
 *    // First get a note object from the factory
 *    var note = Notes.get({ id:$routeParams.id });
 *    $id = note.id;
 *
 *    // Now call update passing in the ID first then the object you are updating
 *    Notes.update({ id:$id }, note);
 *
 *    // This will PUT /notes/ID with the note object in the request payload
 *    }]);
 * ```
 *
 * @example
 *
 * ### Cancelling requests
 *
 * If an action's configuration specifies that it is cancellable, you can cancel the request related
 * to an instance or collection (as long as it is a result of a "non-instance" call):
 *
   ```js
     // ...defining the `Hotel` resource...
     var Hotel = $resource('/api/hotel/:id', {id: '@id'}, {
       // Let's make the `query()` method cancellable
       query: {method: 'get', isArray: true, cancellable: true}
     });

     // ...somewhere in the PlanVacationController...
     ...
     this.onDestinationChanged = function onDestinationChanged(destination) {
       // We don't care about any pending request for hotels
       // in a different destination any more
       this.availableHotels.$cancelRequest();

       // Let's query for hotels in '<destination>'
       // (calls: /api/hotel?location=<destination>)
       this.availableHotels = Hotel.query({location: destination});
     };
   ```
 *

    /**
     * @ngdoc property
     * @name $resourceProvider#defaults
     * @description
     * Object containing default options used when creating `$resource` instances.
     *
     * The default values satisfy a wide range of usecases, but you may choose to overwrite any of
     * them to further customize your instances. The available properties are:
     *
     * - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
     *   calculated URL will be stripped.<br />
     *   (Defaults to true.)
     * - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
     *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
     *   value. For more details, see {@link ngResource.$resource}. This can be overwritten per
     *   resource class or action.<br />
     *   (Defaults to false.)
     * - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
     *   high-level methods corresponding to RESTful actions/methods on resources. An action may
     *   specify what HTTP method to use, what URL to hit, if the return value will be a single
     *   object or a collection (array) of objects etc. For more details, see
     *   {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
     *   class.<br />
     *   The default actions are:
     *   ```js
     *   {
     *     get: {method: 'GET'},
     *     save: {method: 'POST'},
     *     query: {method: 'GET', isArray: true},
     *     remove: {method: 'DELETE'},
     *     delete: {method: 'DELETE'}
     *   }
     *   ```
     *
     * #### Example
     *
     * For example, you can specify a new `update` action that uses the `PUT` HTTP verb:
     *
     * ```js
     *   angular.
     *     module('myApp').
     *     config(['$resourceProvider', function ($resourceProvider) {
     *       $resourceProvider.defaults.actions.update = {
     *         method: 'PUT'
     *       };
     *     }]);
     * ```
     *
     * Or you can even overwrite the whole `actions` list and specify your own:
     *
     * ```js
     *   angular.
     *     module('myApp').
     *     config(['$resourceProvider', function ($resourceProvider) {
     *       $resourceProvider.defaults.actions = {
     *         create: {method: 'POST'},
     *         get:    {method: 'GET'},
     *         getAll: {method: 'GET', isArray:true},
     *         update: {method: 'PUT'},
     *         delete: {method: 'DELETE'}
     *       };
     *     });
     * ```
     *

   * @ngdoc function
   * @name ui.router.util.$resolve#resolve
   * @methodOf ui.router.util.$resolve
   *
   * @description
   * Resolves a set of invocables. An invocable is a function to be invoked via 
   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
   * An invocable can either return a value directly,
   * or a `$q` promise. If a promise is returned it will be resolved and the 
   * resulting value will be used instead. Dependencies of invocables are resolved 
   * (in this order of precedence)
   *
   * - from the specified `locals`
   * - from another invocable that is part of this `$resolve` call
   * - from an invocable that is inherited from a `parent` call to `$resolve` 
   *   (or recursively
   * - from any ancestor `$resolve` of that parent).
   *
   * The return value of `$resolve` is a promise for an object that contains 
   * (in this order of precedence)
   *
   * - any `locals` (if specified)
   * - the resolved return values of all injectables
   * - any values inherited from a `parent` call to `$resolve` (if specified)
   *
   * The promise will resolve after the `parent` promise (if any) and all promises 
   * returned by injectables have been resolved. If any invocable 
   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
   * same error. A rejection of a `parent` promise (if specified) will likewise be 
   * propagated immediately. Once the `$resolve` promise has been rejected, no 
   * further invocables will be called.
   * 
   * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
   * to throw an error. As a special case, an injectable can depend on a parameter 
   * with the same name as the injectable, which will be fulfilled from the `parent` 
   * injectable of the same name. This allows inherited values to be decorated. 
   * Note that in this case any other injectable in the same `$resolve` with the same
   * dependency would see the decorated value, not the inherited value.
   *
   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
   * exception.
   *
   * Invocables are invoked eagerly as soon as all dependencies are available. 
   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
   *
   * As a special case, an invocable can be a string, in which case it is taken to 
   * be a service name to be passed to `$injector.get()`. This is supported primarily 
   * for backwards-compatibility with the `resolve` property of `$routeProvider` 
   * routes.
   *
   * @param {object} invocables functions to invoke or 
   * `$injector` services to fetch.
   * @param {object} locals  values to make available to the injectables
   * @param {object} parent  a promise returned by another call to `$resolve`.
   * @param {object} self  the `this` for the invoked methods
   * @return {object} Promise for an object that contains the resolved return value
   * of all invocables, as well as any inherited and local values.

/**
 * @ngdoc object
 * @name ui.router.util.type:UrlMatcher
 *
 * @description
 * Matches URLs against patterns and extracts named parameters from the path or the search
 * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
 * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
 * do not influence whether or not a URL is matched, but their values are passed through into
 * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
 *
 * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
 * syntax, which optionally allows a regular expression for the parameter to be specified:
 *
 * * `':'` name - colon placeholder
 * * `'*'` name - catch-all placeholder
 * * `'{' name '}'` - curly placeholder
 * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
 *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
 *
 * Parameter names may contain only word characters (latin letters, digits, and underscore) and
 * must be unique within the pattern (across both path and search parameters). For colon
 * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
 * number of characters other than '/'. For catch-all placeholders the path parameter matches
 * any number of characters.
 *
 * Examples:
 *
 * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
 *   trailing slashes, and patterns have to match the entire path, not just a prefix.
 * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
 *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
 * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
 * * `'/user/{id:[^/]*}'` - Same as the previous example.
 * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
 *   parameter consists of 1 to 8 hex digits.
 * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
 *   path into the parameter 'path'.
 * * `'/files/*path'` - ditto.
 * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
 *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
 *
 * @param {string} pattern  The pattern to compile into a matcher.
 * @param {Object} config  A configuration object hash:
 * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
 *   an existing UrlMatcher
 *
 * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
 * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
 *
 * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
 *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
 *   non-null) will start with this prefix.
 *
 * @property {string} source  The pattern that was passed into the constructor
 *
 * @property {string} sourcePath  The path portion of the source property
 *
 * @property {string} sourceSearch  The search portion of the source property
 *
 * @property {string} regex  The constructed regex that will be used to match against the url when
 *   it is time to determine which url will match.
 *
 * @returns {Object}  New `UrlMatcher` object

   *
   * @param {string} name  The type name.
   * @param {Object|Function} definition   The type definition. See
   *        {@link ui.router.util.type:Type `Type`} for information on the values accepted.
   * @param {Object|Function} definitionFn (optional) A function that is injected before the app
   *        runtime starts.  The result of this function is merged into the existing `definition`.
   *        See {@link ui.router.util.type:Type `Type`} for information on the values accepted.
   *
   * @returns {Object}  Returns `$urlMatcherFactoryProvider`.
   *
   * @example
   * This is a simple example of a custom type that encodes and decodes items from an
   * array, using the array index as the URL-encoded value:
   *
   * <pre>
   * var list = ['John', 'Paul', 'George', 'Ringo'];
   *
   * $urlMatcherFactoryProvider.type('listItem', {
   *   encode: function(item) {
   *     // Represent the list item in the URL using its corresponding index
   *     return list.indexOf(item);
   *   },
   *   decode: function(item) {
   *     // Look up the list item by index
   *     return list[parseInt(item, 10)];
   *   },
   *   is: function(item) {
   *     // Ensure the item is valid by checking to see that it appears
   *     // in the list
   *     return list.indexOf(item) > -1;
   *   }
   * });
   *
   * $stateProvider.state('list', {
   *   url: "/list/{item:listItem}",
   *   controller: function($scope, $stateParams) {
   *     console.log($stateParams.item);
   *   }
   * });
   *
   * // ...
   *
   * // Changes URL to '/list/3', logs "Ringo" to the console
   * $state.go('list', { item: "Ringo" });
   * </pre>
   *
   * This is a more complex example of a type that relies on dependency injection to
   * interact with services, and uses the parameter name from the URL to infer how to
   * handle encoding and decoding parameter values:
   *
   * <pre>
   * // Defines a custom type that gets a value from a service,
   * // where each service gets different types of values from
   * // a backend API:
   * $urlMatcherFactoryProvider.type('dbObject', {}, function(Users, Posts) {
   *
   *   // Matches up services to URL parameter names
   *   var services = {
   *     user: Users,
   *     post: Posts
   *   };
   *
   *   return {
   *     encode: function(object) {
   *       // Represent the object in the URL using its unique ID
   *       return object.id;
   *     },
   *     decode: function(value, key) {
   *       // Look up the object by ID, using the parameter
   *       // name (key) to call the correct service
   *       return services[key].findById(value);
   *     },
   *     is: function(object, key) {
   *       // Check that object is a valid dbObject
   *       return angular.isObject(object) && object.id && services[key];
   *     }
   *     equals: function(a, b) {
   *       // Check the equality of decoded objects by comparing
   *       // their unique IDs
   *       return a.id === b.id;
   *     }
   *   };
   * });
   *
   * // In a config() block, you can then attach URLs with
   * // type-annotated parameters:
   * $stateProvider.state('users', {
   *   url: "/users",
   *   // ...
   * }).state('users.item', {
   *   url: "/{user:dbObject}",

  /**
   * @ngdoc function
   * @name ui.router.state.$stateProvider#decorator
   * @methodOf ui.router.state.$stateProvider
   *
   * @description
   * Allows you to extend (carefully) or override (at your own peril) the 
   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
   * to add custom functionality to ui-router, for example inferring templateUrl 
   * based on the state name.
   *
   * When passing only a name, it returns the current (original or decorated) builder
   * function that matches `name`.
   *
   * The builder functions that can be decorated are listed below. Though not all
   * necessarily have a good use case for decoration, that is up to you to decide.
   *
   * In addition, users can attach custom decorators, which will generate new 
   * properties within the state's internal definition. There is currently no clear 
   * use-case for this beyond accessing internal states (i.e. $state.$current), 
   * however, expect this to become increasingly relevant as we introduce additional 
   * meta-programming features.
   *
   * **Warning**: Decorators should not be interdependent because the order of 
   * execution of the builder functions in non-deterministic. Builder functions 
   * should only be dependent on the state definition object and super function.
   *
   *
   * Existing builder functions and current return values:
   *
   * - **parent** `{object}` - returns the parent state object.
   * - **data** `{object}` - returns state data, including any inherited data that is not
   *   overridden by own values (if any).
   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
   *   or `null`.
   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
   *   navigable).
   * - **params** `{object}` - returns an array of state params that are ensured to 
   *   be a super-set of parent's params.
   * - **views** `{object}` - returns a views object where each key is an absolute view 
   *   name (i.e. "viewName@stateName") and each value is the config object 
   *   (template, controller) for the view. Even when you don't use the views object 
   *   explicitly on a state config, one is still created for you internally.
   *   So by decorating this builder function you have access to decorating template 
   *   and controller properties.
   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
   *   not including any params defined by ancestor states.
   * - **path** `{string}` - returns the full path from the root down to this state. 
   *   Needed for state activation.
   * - **includes** `{object}` - returns an object that includes every state that 
   *   would pass a `$state.includes()` test.
   *
   * @example
   * <pre>
   * // Override the internal 'views' builder with a function that takes the state
   * // definition, and a reference to the internal function being overridden:
   * $stateProvider.decorator('views', function (state, parent) {
   *   var result = {},
   *       views = parent(state);
   *
   *   angular.forEach(views, function (config, name) {
   *     var autoName = (state.name + '.' + name).replace('.', '/');
   *     config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
   *     result[name] = config;
   *   });
   *   return result;
   * });
   *
   * $stateProvider.state('home', {
   *   views: {
   *     'contact.list': { controller: 'ListController' },
   *     'contact.item': { controller: 'ItemController' }
   *   }
   * });
   *
   * // ...
   *
   * $state.go('home');
   * // Auto-populates list and item views with /partials/home/contact/list.html,
   * // and /partials/home/contact/item.html, respectively.

   *
   * @description
   * Registers a state configuration under a given state name. The stateConfig object

   *
   *   path or function that returns a path to an html
   *   template that should be used by uiView.
   *   
   *   If `templateUrl` is a function, it will be called with the following parameters:
   *
   *   - {array.&lt;object&gt;} - state parameters extracted from the current $location.path() by 
   *     applying the current state
   *
   * <pre>templateUrl: "home.html"</pre>

   *
   * @param {string|function=} stateConfig.controller
   * <a id='controller'></a>
   *
   *  Controller fn that should be associated with newly
   *   related scope or the name of a registered controller if passed as a string.
   *   Optionally, the ControllerAs may be declared here.
   * <pre>controller: "MyRegisteredController"</pre>
   * <pre>controller:

   *
   * @param {string=} stateConfig.controllerAs
   * <a id='controllerAs'></a>
   * 
   * A controller alias name. If present the controller will be
   *   published to scope under the controllerAs name.
   * <pre>controllerAs: "myCtrl"</pre>
   *
   * @param {string|object=} stateConfig.parent
   * <a id='parent'></a>

   * <pre>parent: parentState // JS variable</pre>
   *
   * @param {object=} stateConfig.resolve
   * <a id='resolve'></a>
   *
   * An optional map&lt;string, function&gt; of dependencies which
   *   should be injected into the controller. If any of these dependencies are promises, 
   *   the router will wait for them all to be resolved before the controller is instantiated.
   *   If all the promises are resolved successfully, the $stateChangeSuccess event is fired
   *   and the values of the resolved promises are injected into any controllers that reference them.
   *   If any  of the promises are rejected the $stateChangeError event is fired.
   *
   *   The map object is:
   *   
   *   - key - {string}: name of dependency to be injected into controller
   *   - factory - {string|function}: If string then it is alias for service. Otherwise if function, 
   *     it is injected and return value it treated as dependency. If result is a promise, it is 
   *     resolved before its value is injected into controller.
   *
   * <pre>resolve: {
   *     myResolve1:

   *         return $http.get("/api/foos/"+stateParams.fooID);
   *       }
   *     }</pre>
   *
   * @param {string=} stateConfig.url
   * <a id='url'></a>
   *
   *   A url fragment with optional parameters. When a state is navigated or
   *   transitioned to, the `$stateParams` service will be populated with any 
   *   parameters that were passed.
   *
   *   (See {@link ui.router.util.type:UrlMatcher UrlMatcher} `UrlMatcher`} for
   *   more details on acceptable patterns )
   *
   * examples:
   * <pre>url: "/home"

   * url: "/books/{bookid:[a-zA-Z_-]}"
   * url: "/books/{categoryid:int}"
   * url: "/books/{publishername:string}/{categoryid:int}"
   * url: "/messages?before&after"
   * url: "/messages?{before:date}&{after:date}"
   * url: "/messages/:mailboxid?{before:date}&{after:date}"
   * </pre>
   *
   * @param {object=} stateConfig.views
   * <a id='views'></a>
   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
   * manually/explicitly.
   *
   * Examples:
   *
   * Targets three named `ui-view`s in the parent state's template
   * <pre>views: {
   *     header: {
   *       controller: "headerCtrl",
   *       templateUrl: "header.html"
   *     }, body: {
   *       controller: "bodyCtrl",
   *       templateUrl: "body.html"
   *     }, footer: {
   *       controller: "footCtrl",
   *       templateUrl: "footer.html"
   *     }
   *   }</pre>
   *
   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
   * <pre>views: {
   *     'header@top': {
   *       controller: "msgHeaderCtrl",
   *       templateUrl: "msgHeader.html"
   *     }, 'body': {
   *       controller: "messagesCtrl",
   *       templateUrl: "messages.html"
   *     }
   *   }</pre>
   *
   * @param {boolean=} [stateConfig.abstract=false]
   * <a id='abstract'></a>
   * An abstract state will never be directly activated,
   *   but can provide inherited properties to its common children states.
   * <pre>abstract: true</pre>
   *
   * @param {function=} stateConfig.onEnter
   * <a id='onEnter'></a>
   *
   * Callback function for when a state is entered. Good way
   *   to trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onEnter: function(MyService, $stateParams) {
   *     MyService.foo($stateParams.myParam);
   * }</pre>
   *
   * @param {function=} stateConfig.onExit
   * <a id='onExit'></a>
   *
   * Callback function for when a state is exited. Good way to
   *   trigger an action or dispatch an event, such as opening a dialog.
   * If minifying your scripts, make sure to explicitly annotate this function,
   * because it won't be automatically annotated by your build tools.
   *
   * <pre>onExit: function(MyService, $stateParams) {
   *     MyService.cleanup($stateParams.myParam);
   * }</pre>
   *
   * @param {boolean=} [stateConfig.reloadOnSearch=true]
   * <a id='reloadOnSearch'></a>
   *
   * If `false`, will not retrigger the same state
   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
   *   Useful for when you'd like to modify $location.search() without triggering a reload.
   * <pre>reloadOnSearch: false</pre>
   *
   * @param {object=} stateConfig.data
   * <a id='data'></a>
   *
   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
   *   prototypally inherited.  In other words, adding a data property to a state adds it to
   *   the entire subtree via prototypal inheritance.
   *
   * <pre>data: {
   *     requiredRole: 'foo'
   * } </pre>
   *
   * @param {object=} stateConfig.params
   * <a id='params'></a>
   *
   * A map which optionally configures parameters declared in the `url`, or
   *   defines additional non-url parameters.  For each parameter being
   *   configured, add a configuration object keyed to the name of the parameter.
   *
   *   Each parameter configuration object may contain the following properties:
   *
   *   - ** value ** - {object|function=}: specifies the default value for this
   *     parameter.  This implicitly sets this parameter as optional.
   *
   *     When UI-Router routes to a state and no value is
   *     specified for this parameter in the URL or transition, the
   *     default value will be used instead.  If `value` is a function,
   *     it will be injected and invoked, and the return value used.
   *
   *     *Note*: `undefined` is treated as "no default value" while `null`
   *     is treated as "the default value is `null`".
   *
   *     *Shorthand*: If you only need to configure the default value of the
   *     parameter, you may use a shorthand syntax.   In the **`params`**
   *     map, instead mapping the param name to a full parameter configuration
   *     object, simply set map it to the default parameter value, e.g.:
   *
   * <pre>// define a parameter's default value
   * params: {
   *     param1: { value: "defaultValue" }
   * }
   * // shorthand default values
   * params: {
   *     param1: "defaultValue",
   *     param2: "param2Default"
   * }</pre>
   *
   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
   *     treated as an array of values.  If you specified a Type, the value will be
   *     treated as an array of the specified Type.  Note: query parameter values
   *     default to a special `"auto"` mode.
   *
   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
   *     value (e.g.: `{ foo: '1' }`).
   *
   * <pre>params: {
   *     param1: { array: true }
   * }</pre>
   *
   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
   *     configured default squash policy.
   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
   *
   *   There are three squash settings:
   *
   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
   *       This can allow for cleaner looking URLs.
   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
   *
   * <pre>params: {
   *     param1: {
   *       value: "defaultId",
   *       squash: true
   * } }
   * // squash "defaultValue" to "~"
   * params: {
   *     param1: {
   *       value: "defaultValue",
   *       squash: "~"
   * } }
   * </pre>
   *
   *
   * @example
   * <pre>
   * // Some state name examples
   *
   * // stateName can be a single top-level name (must be unique).
   * $stateProvider.state("home", {});
   *
   * // Or it can be a nested state name. This state is a child of the
   * // above "home" state.
   * $stateProvider.state("home.newest", {});
   *
   * // Nest states as deeply as needed.
   * $stateProvider.state("home.newest.abc.xyz.inception", {});
   *
   * // state() returns $stateProvider, so you can chain state declarations.
   * $stateProvider
   *   .state("home", {})
   *   .state("about", {})
   *   .state("contacts", {});

       * @param {Object} unfoundState Unfound State information. Contains: `to, toParams, options` properties.

     * @methodOf ui.router.state.$state
     *
     * @description
     * Convenience method for transitioning to a new state. `$state.go` calls 
     * `$state.transitionTo` internally but automatically sets options to 
     * `{ location: true, inherit: true, relative: $state.$current, notify: true }`. 
     * This allows you to easily use an absolute or relative to path and specify 
     * only the parameters you'd like to update (while letting unspecified parameters 
     * inherit from the currently active ancestor states).
     *
     * @example
     * <pre>
     * var app = angular.module('app', ['ui.router']);
     *
     * app.controller('ctrl', function ($scope, $state) {
     *   $scope.changeState = function () {
     *     $state.go('contact.detail');
     *   };
     * });
     * </pre>
     * <img src='../ngdoc_assets/StateGoExamples.png'/>
     *
     * @param {string} to Absolute state name or relative state path. Some examples:
     *
     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
     * - `$state.go('^')` - will go to a parent state
     * - `$state.go('^.sibling')` - will go to a sibling state
     * - `$state.go('.child.grandchild')` - will go to grandchild state
     *
     * @param {object=} params A map of the parameters that will be sent to the state, 
     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
     * defined parameters. Only parameters specified in the state definition can be overridden, new 
     * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
     * will get you all current parameters, etc.
     * @param {object=} options Options object. The options are:
     *
     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
     *    defines which state to be relative from.
     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
     * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
     *    have changed.  It will reload the resolves and views of the current state and parent states.
     *    If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
     *    the transition reloads the resolves and views for that matched state, and all its children states.
     *
     * @returns {promise} A promise representing the state of the new transition.
     *
     * Possible success values:
     *
     * - $state.current
     *
     * <br/>Possible rejection values:
     *
     * - 'transition superseded' - when a newer transition has been started after this one
     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
     *   when a `$stateNotFound` `event.retry` promise errors.
     * - 'transition failed' - when a state has been unsuccessfully found after 2 tries.
     * - *resolve error* - when an error has occurred with a `resolve`

 * @requires $document
 *
 * @restrict ECA
 *
 * @description
 * The ui-view directive tells $state where to place your templates.
 *
 * @param {string=} name A view name. The name should be unique amongst the other views in the
 * same state. You can have views of the same name that live in different states.
 *
 * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
 * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
 * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
 * scroll ui-view elements into view when they are populated during a state activation.
 *
 * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
 * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
 *
 * @param {string=} onload Expression to evaluate whenever the view updates.
 *
 * @example
 * A view can be unnamed or named.
 * <pre>
 * <!-- Unnamed -->
 * <div ui-view></div>
 *
 * <!-- Named -->
 * <div ui-view="viewName"></div>
 * </pre>
 *
 * You can only have one unnamed view within any template (or root html). If you are only using a
 * single view and it is unnamed then you can populate it like so:
 * <pre>
 * <div ui-view></div>
 * $stateProvider.state("home", {
 *   template: "<h1>HELLO!</h1>"
 * })
 * </pre>
 *
 * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#methods_state `views`}
 * config property, by name, in this case an empty name:
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * But typically you'll only use the views property if you name your view or have more than one view
 * in the same template. There's not really a compelling reason to name a view if its the only one,
 * but you could if you wanted, like so:
 * <pre>
 * <div ui-view="main"></div>
 * </pre>
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "main": {
 *       template: "<h1>HELLO!</h1>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Really though, you'll use views to set up multiple views:
 * <pre>
 * <div ui-view></div>
 * <div ui-view="chart"></div>
 * <div ui-view="data"></div>
 * </pre>
 *
 * <pre>
 * $stateProvider.state("home", {
 *   views: {
 *     "": {
 *       template: "<h1>HELLO!</h1>"
 *     },
 *     "chart": {
 *       template: "<chart_thing/>"
 *     },
 *     "data": {
 *       template: "<data_thing/>"
 *     }
 *   }    
 * })
 * </pre>
 *
 * Examples for `autoscroll`:
 *
 * <pre>
 * <!-- If autoscroll present with no expression,
 *      then scroll ui-view into view -->
 * <ui-view autoscroll/>
 *
 * <!-- If autoscroll present with valid expression,
 *      then scroll ui-view into view if expression evaluates to true -->
 * <ui-view autoscroll='true'/>
 * <ui-view autoscroll='false'/>
 * <ui-view autoscroll='scopeVariable'/>
 * </pre>
 *
 * Resolve data:
 *
 * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
 * can be customized using [[ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
 *
 * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
 * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
 * depends on `$resolve` data.
 *
 * Example usage of $resolve in a view template
 * <pre>
 * $stateProvider.state('home', {
 *   template: '<my-component user="$resolve.user"></my-component>',
 *   resolve: {
 *     user: function(UserService) { return UserService.fetchUser(); }
 *   }
 * });
 * </pre>

 * @ngdoc directive

 *
 * @restrict A
 *
 * @description
 * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
 * URL, the directive will automatically generate & update the `href` attribute via
 * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
 * the link will trigger a state transition with optional parameters.
 *
 * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
 * handled natively by the browser.
 *
 * You can also use relative state paths within ui-sref, just like the relative
 * paths passed to `$state.go()`. You just need to be aware that the path is relative
 * to the state that the link lives in, in other words the state that loaded the
 * template containing the link.
 *
 * You can specify options to pass to {@link ui.router.state.$state#methods_go $state.go()}
 * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
 * and `reload`.
 *
 * @example
 * Here's an example of how you'd use ui-sref and how it would compile. If you have the
 * following template:
 * <pre>
 * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
 *     </li>
 * </ul>
 * </pre>
 *
 * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
 * <pre>
 * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
 *
 * <ul>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>
 *     </li>
 *     <li ng-repeat="contact in contacts">
 *         <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>
 *     </li>
 * </ul>
 *
 * <a ui-sref="home" ui-sref-opts="{reload: true}">Home</a>
 * </pre>

/**
 * @ngdoc directive
 * @name ui.router.state.directive:ui-sref-active
 *
 * @requires ui.router.state.$state
 * @requires ui.router.state.$stateParams
 * @requires $interpolate
 *
 * @restrict A
 *
 * @description
 * A directive working alongside ui-sref to add classes to an element when the
 * related ui-sref directive's state is active, and removing them when it is inactive.
 * The primary use-case is to simplify the special appearance of navigation menus
 * relying on `ui-sref`, by having the "active" state's menu button appear different,
 * distinguishing it from the inactive menu items.
 *
 * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
 * ui-sref-active found at the same level or above the ui-sref will be used.
 *
 * Will activate when the ui-sref's target state or any child state is active. If you
 * need to activate only when the ui-sref target state is active and *not* any of
 * it's children, then you will use
 * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
 *
 * @example
 * Given the following template:
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item">
 *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 *
 * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
 * the resulting HTML will appear as (note the 'active' class):
 * <pre>
 * <ul>
 *   <li ui-sref-active="active" class="item active">
 *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * The class name is interpolated **once** during the directives link time (any further changes to the
 * interpolated value are ignored).
 *
 * Multiple classes may be specified in a space-separated format:
 * <pre>
 * <ul>
 *   <li ui-sref-active='class1 class2 class3'>
 *     <a ui-sref="app.user">link</a>
 *   </li>
 * </ul>
 * </pre>
 *
 * It is also possible to pass ui-sref-active an expression that evaluates
 * to an object hash, whose keys represent active class names and whose
 * values represent the respective state names/globs.
 * ui-sref-active will match if the current active state **includes** any of
 * the specified state names/globs, even the abstract ones.
 *
 * @Example
 * Given the following template, with "admin" being an abstract state:
 * <pre>
 * <div ui-sref-active="{'active': 'admin.*'}">
 *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
 * </div>
 * </pre>
 *
 * When the current state is "admin.roles" the "active" class will be applied
 * to both the <div> and <a> elements. It is important to note that the state
 * names/globs passed to ui-sref-active shadow the state provided by ui-sref.

/**
 * Performs initialization, ie: precomputes tables to optimize for speed.
 *
 * One way to understand how AES works is to imagine that 'addition' and
 * 'multiplication' are interfaces that require certain mathematical
 * properties to hold true (ie: they are associative) but they might have
 * different implementations and produce different kinds of results ...
 * provided that their mathematical properties remain true. AES defines
 * its own methods of addition and multiplication but keeps some important
 * properties the same, ie: associativity and distributivity. The
 * explanation below tries to shed some light on how AES defines addition
 * and multiplication of bytes and 32-bit words in order to perform its
 * encryption and decryption algorithms.
 *
 * The basics:
 *
 * The AES algorithm views bytes as binary representations of polynomials
 * that have either 1 or 0 as the coefficients. It defines the addition
 * or subtraction of two bytes as the XOR operation. It also defines the
 * multiplication of two bytes as a finite field referred to as GF(2^8)
 * (Note: 'GF' means "Galois Field" which is a field that contains a finite
 * number of elements so GF(2^8) has 256 elements).
 *
 * This means that any two bytes can be represented as binary polynomials;
 * when they multiplied together and modularly reduced by an irreducible
 * polynomial of the 8th degree, the results are the field GF(2^8). The
 * specific irreducible polynomial that AES uses in hexadecimal is 0x11b.
 * This multiplication is associative with 0x01 as the identity:
 *
 * (b * 0x01 = GF(b, 0x01) = b).
 *
 * The operation GF(b, 0x02) can be performed at the byte level by left
 * shifting b once and then XOR'ing it (to perform the modular reduction)
 * with 0x11b if b is >= 128. Repeated application of the multiplication
 * of 0x02 can be used to implement the multiplication of any two bytes.
 *
 * For instance, multiplying 0x57 and 0x13, denoted as GF(0x57, 0x13), can
 * be performed by factoring 0x13 into 0x01, 0x02, and 0x10. Then these
 * factors can each be multiplied by 0x57 and then added together. To do
 * the multiplication, values for 0x57 multiplied by each of these 3 factors
 * can be precomputed and stored in a table. To add them, the values from
 * the table are XOR'd together.
 *
 * AES also defines addition and multiplication of words, that is 4-byte
 * numbers represented as polynomials of 3 degrees where the coefficients
 * are the values of the bytes.
 *
 * The word [a0, a1, a2, a3] is a polynomial a3x^3 + a2x^2 + a1x + a0.
 *
 * Addition is performed by XOR'ing like powers of x. Multiplication
 * is performed in two steps, the first is an algebriac expansion as
 * you would do normally (where addition is XOR). But the result is
 * a polynomial larger than 3 degrees and thus it cannot fit in a word. So
 * next the result is modularly reduced by an AES-specific polynomial of
 * degree 4 which will always produce a polynomial of less than 4 degrees
 * such that it will fit in a word. In AES, this polynomial is x^4 + 1.
 *
 * The modular product of two polynomials 'a' and 'b' is thus:
 *
 * d(x) = d3x^3 + d2x^2 + d1x + d0
 * with
 * d0 = GF(a0, b0) ^ GF(a3, b1) ^ GF(a2, b2) ^ GF(a1, b3)
 * d1 = GF(a1, b0) ^ GF(a0, b1) ^ GF(a3, b2) ^ GF(a2, b3)
 * d2 = GF(a2, b0) ^ GF(a1, b1) ^ GF(a0, b2) ^ GF(a3, b3)
 * d3 = GF(a3, b0) ^ GF(a2, b1) ^ GF(a1, b2) ^ GF(a0, b3)
 *
 * As a matrix:
 *
 * [d0] = [a0 a3 a2 a1][b0]
 * [d1]   [a1 a0 a3 a2][b1]
 * [d2]   [a2 a1 a0 a3][b2]
 * [d3]   [a3 a2 a1 a0][b3]
 *
 * Special polynomials defined by AES (0x02 == {02}):
 * a(x)    = {03}x^3 + {01}x^2 + {01}x + {02}
 * a^-1(x) = {0b}x^3 + {0d}x^2 + {09}x + {0e}.
 *
 * These polynomials are used in the MixColumns() and InverseMixColumns()
 * operations, respectively, to cause each element in the state to affect
 * the output (referred to as diffusing).
 *
 * RotWord() uses: a0 = a1 = a2 = {00} and a3 = {01}, which is the
 * polynomial x3.
 *
 * The ShiftRows() method modifies the last 3 rows in the state (where
 * the state is 4 words with 4 bytes per word) by shifting bytes cyclically.
 * The 1st byte in the second row is moved to the end of the row. The 1st
 * and 2nd bytes in the third row are moved to the end of the row. The 1st,
 * 2nd, and 3rd bytes are moved in the fourth row.
 *
 * More details on how AES arithmetic works:
 *
 * In the polynomial representation of binary numbers, XOR performs addition
 * and subtraction and multiplication in GF(2^8) denoted as GF(a, b)
 * corresponds with the multiplication of polynomials modulo an irreducible
 * polynomial of degree 8. In other words, for AES, GF(a, b) will multiply
 * polynomial 'a' with polynomial 'b' and then do a modular reduction by
 * an AES-specific irreducible polynomial of degree 8.
 *
 * A polynomial is irreducible if its only divisors are one and itself. For
 * the AES algorithm, this irreducible polynomial is:
 *
 * m(x) = x^8 + x^4 + x^3 + x + 1,
 *
 * or {01}{1b} in hexadecimal notation, where each coefficient is a bit:
 * 100011011 = 283 = 0x11b.
 *
 * For example, GF(0x57, 0x83) = 0xc1 because
 *
 * 0x57 = 87  = 01010111 = x^6 + x^4 + x^2 + x + 1
 * 0x85 = 131 = 10000101 = x^7 + x + 1
 *
 * (x^6 + x^4 + x^2 + x + 1) * (x^7 + x + 1)
 * =  x^13 + x^11 + x^9 + x^8 + x^7 +
 *    x^7 + x^5 + x^3 + x^2 + x +
 *    x^6 + x^4 + x^2 + x + 1
 * =  x^13 + x^11 + x^9 + x^8 + x^6 + x^5 + x^4 + x^3 + 1 = y
 *    y modulo (x^8 + x^4 + x^3 + x + 1)
 * =  x^7 + x^6 + 1.
 *
 * The modular reduction by m(x) guarantees the result will be a binary
 * polynomial of less than degree 8, so that it can fit in a byte.
 *
 * The operation to multiply a binary polynomial b with x (the polynomial
 * x in binary representation is 00000010) is:
 *
 * b_7x^8 + b_6x^7 + b_5x^6 + b_4x^5 + b_3x^4 + b_2x^3 + b_1x^2 + b_0x^1
 *
 * To get GF(b, x) we must reduce that by m(x). If b_7 is 0 (that is the
 * most significant bit is 0 in b) then the result is already reduced. If
 * it is 1, then we can reduce it by subtracting m(x) via an XOR.
 *
 * It follows that multiplication by x (00000010 or 0x02) can be implemented
 * by performing a left shift followed by a conditional bitwise XOR with
 * 0x1b. This operation on bytes is denoted by xtime(). Multiplication by
 * higher powers of x can be implemented by repeated application of xtime().
 *
 * By adding intermediate results, multiplication by any constant can be
 * implemented. For instance:
 *
 * GF(0x57, 0x13) = 0xfe because:
 *
 * xtime(b) = (b & 128) ? (b << 1 ^ 0x11b) : (b << 1)
 *
 * Note: We XOR with 0x11b instead of 0x1b because in javascript our
 * datatype for b can be larger than 1 byte, so a left shift will not
 * automatically eliminate bits that overflow a byte ... by XOR'ing the
 * overflow bit with 1 (the extra one from 0x11b) we zero it out.
 *
 * GF(0x57, 0x02) = xtime(0x57) = 0xae
 * GF(0x57, 0x04) = xtime(0xae) = 0x47
 * GF(0x57, 0x08) = xtime(0x47) = 0x8e
 * GF(0x57, 0x10) = xtime(0x8e) = 0x07
 *
 * GF(0x57, 0x13) = GF(0x57, (0x01 ^ 0x02 ^ 0x10))
 *
 * And by the distributive property (since XOR is addition and GF() is
 * multiplication):
 *
 * = GF(0x57, 0x01) ^ GF(0x57, 0x02) ^ GF(0x57, 0x10)
 * = 0x57 ^ 0xae ^ 0x07
 * = 0xfe.

      all of the elements in GF, find their multiplicative inverses,
      and apply to each the following affine transformation:

      bi' = bi ^ b(i + 4) mod 8 ^ b(i + 5) mod 8 ^ b(i + 6) mod 8 ^
            b(i + 7) mod 8 ^ ci
      for 0 <= i < 8, where bi is the ith bit of the byte, and ci is the
      ith bit of a byte c with the value {63} or {01100011}.

      It is possible to traverse every possible value in a Galois field
      using what is referred to as a 'generator'. There are many
      generators (128 out of 256): 3,5,6,9,11,82 to name a few. To fully
      traverse GF we iterate 255 times, multiplying by our generator
      each time.

      On each iteration we can determine the multiplicative inverse for
      the current element.

      Suppose there is an element in GF 'e'. For a given generator 'g',
      e = g^x. The multiplicative inverse of e is g^(255 - x). It turns
      out that if use the inverse of a generator as another generator
      it will produce all of the corresponding multiplicative inverses
      at the same time. For this reason, we choose 5 as our inverse
      generator because it only requires 2 multiplies and 1 add and its
      inverse, 82, requires relatively few operations as well.

      In order to apply the affine transformation, the multiplicative
      inverse 'ei' of 'e' can be repeatedly XOR'd (4 times) with a
      bit-cycling of 'ei'. To do this 'ei' is first stored in 's' and
      'x'. Then 's' is left shifted and the high bit of 's' is made the
      low bit. The resulting value is stored in 's'. Then 'x' is XOR'd
      with 's' and stored in 'x'. On each subsequent iteration the same
      operation is performed. When 4 iterations are complete, 'x' is
      XOR'd with 'c' (0x63) and the transformed value is stored in 'x'.
      For example:

      s = 01000001
      x = 01000001

      iteration 1: s = 10000010, x ^= s
      iteration 2: s = 00000101, x ^= s
      iteration 3: s = 00001010, x ^= s
      iteration 4: s = 00010100, x ^= s
      x ^= 0x63

      This can be done with a loop where s = (s << 1) | (s >> 7). However,
      it can also be done by using a single 16-bit (in this case 32-bit)
      number 'sx'. Since XOR is an associative operation, we can set 'sx'
      to 'ei' and then XOR it with 'sx' left-shifted 1,2,3, and 4 times.
      The most significant bits will flow into the high 8 bit positions
      and be correctly XOR'd with one another. All that remains will be
      to cycle the high 8 bits by XOR'ing them all with the lower 8 bits
      afterwards.

      At the same time we're populating sbox and isbox we can precompute
      the multiplication we'll need to do to do MixColumns() later.
    */

    // apply affine transformation
    sx = ei ^ (ei << 1) ^ (ei << 2) ^ (ei << 3) ^ (ei << 4);

    // update tables
    sbox[e] = sx;
    isbox[sx] = e;

    /* Mixing columns is done using matrix multiplication. The columns
      that are to be mixed are each a single word in the current state.
      The state has Nb columns (4 columns). Therefore each column is a
      4 byte word. So to mix the columns in a single column 'c' where
      its rows are r0, r1, r2, and r3, we use the following matrix
      multiplication:

      [2 3 1 1]*[r0,c]=[r'0,c]
      [1 2 3 1] [r1,c] [r'1,c]
      [1 1 2 3] [r2,c] [r'2,c]
      [3 1 1 2] [r3,c] [r'3,c]

      r0, r1, r2, and r3 are each 1 byte of one of the words in the
      state (a column). To do matrix multiplication for each mixed
      column c' we multiply the corresponding row from the left matrix
      with the corresponding column from the right matrix. In total, we
      get 4 equations:

      r0,c' = 2*r0,c + 3*r1,c + 1*r2,c + 1*r3,c
      r1,c' = 1*r0,c + 2*r1,c + 3*r2,c + 1*r3,c
      r2,c' = 1*r0,c + 1*r1,c + 2*r2,c + 3*r3,c
      r3,c' = 3*r0,c + 1*r1,c + 1*r2,c + 2*r3,c

      As usual, the multiplication is as previously defined and the
      addition is XOR. In order to optimize mixing columns we can store
      the multiplication results in tables. If you think of the whole
      column as a word (it might help to visualize by mentally rotating
      the equations above by counterclockwise 90 degrees) then you can
      see that it would be useful to map the multiplications performed on
      each byte (r0, r1, r2, r3) onto a word as well. For instance, we
      could map 2*r0,1*r0,1*r0,3*r0 onto a word by storing 2*r0 in the
      highest 8 bits and 3*r0 in the lowest 8 bits (with the other two
      respectively in the middle). This means that a table can be
      constructed that uses r0 as an index to the word. We can do the
      same with r1, r2, and r3, creating a total of 4 tables.

      To construct a full c', we can just look up each byte of c in
      their respective tables and XOR the results together.

      Also, to build each table we only have to calculate the word
      for 2,1,1,3 for every byte ... which we can do on each iteration
      of this loop since we will iterate over every byte. After we have
      calculated 2,1,1,3 we can get the results for the other tables
      by cycling the byte at the end to the beginning. For instance
      we can take the result of table 2,1,1,3 and produce table 3,2,1,1
      by moving the right most byte to the left most position just like
      how you can imagine the 3 moved out of 2,1,1,3 and to the front
      to produce 3,2,1,1.

      There is another optimization in that the same multiples of
      the current element we need in order to advance our generator
      to the next iteration can be reused in performing the 2,1,1,3
      calculation. We also calculate the inverse mix column tables,
      with e,9,d,b being the inverse of 2,1,1,3.

      When we're done, and we need to actually mix columns, the first
      byte of each state word should be put through mix[0] (2,1,1,3),
      the second through mix[1] (3,2,1,1) and so forth. Then they should
      be XOR'd together to produce the fully mixed column.

   /* When we are updating a cipher block we always use the code path for
     encryption whether we are decrypting or not (to shorten code and
     simplify the generation of look up tables). However, because there
     are differences in the decryption algorithm, other than just swapping
     in different look up tables, we must transform our key schedule to
     account for these changes:

     1. The decryption algorithm gets its key rounds in reverse order.
     2. The decryption algorithm adds the round key before mixing columns
       instead of afterwards.

     We don't need to modify our key schedule to handle the first case,
     we can just traverse the key schedule in reverse order when decrypting.

     The second case requires a little work.

     The tables we built for performing rounds will take an input and then
     perform SubBytes() and MixColumns() or, for the decrypt version,
     InvSubBytes() and InvMixColumns(). But the decrypt algorithm requires
     us to AddRoundKey() before InvMixColumns(). This means we'll need to
     apply some transformations to the round key to inverse-mix its columns
     so they'll be correct for moving AddRoundKey() to after the state has
     had its columns inverse-mixed.

     To inverse-mix the columns of the state when we're decrypting we use a
     lookup table that will apply InvSubBytes() and InvMixColumns() at the
     same time. However, the round key's bytes are not inverse-substituted
     in the decryption algorithm. To get around this problem, we can first
     substitute the bytes in the round key so that when we apply the
     transformation via the InvSubBytes()+InvMixColumns() table, it will
     undo our substitution leaving us with the original value that we
     want -- and then inverse-mix that value.

     This change will correctly alter our key schedule so that we can XOR
     each round key with our already transformed decryption state. This
     allows us to use the same code path as the encryption algorithm.

     We make one more change to the decryption key. Since the decryption
     algorithm runs in reverse from the encryption algorithm, we reverse
     the order of the round keys to avoid having to iterate over the key
     schedule backwards when running the encryption algorithm later in
     decryption mode. In addition to reversing the order of the round keys,
     we also swap each round key's 2nd and 4th rows. See the comments
     section where rounds are performed for more details about why this is
     done. These changes are done inline with the other substitution
     described above.

    order of transformations applied when performing rounds. We also get
    key rounds in reverse order (relative to encryption). */
  for(var round = 1; round < Nr; ++round) {
    /* As described above, we'll be using table lookups to perform the
      column mixing. Each column is stored as a word in the state (the
      array 'input' has one column as a word at each index). In order to
      mix a column, we perform these transformations on each row in c,
      which is 1 byte in each word. The new column for c0 is c'0:

               m0      m1      m2      m3
      r0,c'0 = 2*r0,c0 + 3*r1,c0 + 1*r2,c0 + 1*r3,c0
      r1,c'0 = 1*r0,c0 + 2*r1,c0 + 3*r2,c0 + 1*r3,c0
      r2,c'0 = 1*r0,c0 + 1*r1,c0 + 2*r2,c0 + 3*r3,c0
      r3,c'0 = 3*r0,c0 + 1*r1,c0 + 1*r2,c0 + 2*r3,c0

      So using mix tables where c0 is a word with r0 being its upper
      8 bits and r3 being its lower 8 bits:

      m0[c0 >> 24] will yield this word: [2*r0,1*r0,1*r0,3*r0]
      ...
      m3[c0 & 255] will yield this word: [1*r3,1*r3,3*r3,2*r3]

      Therefore to mix the columns in each word in the state we
      do the following (& 255 omitted for brevity):
      c'0,r0 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
      c'0,r1 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
      c'0,r2 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]
      c'0,r3 = m0[c0 >> 24] ^ m1[c1 >> 16] ^ m2[c2 >> 8] ^ m3[c3]

      However, before mixing, the algorithm requires us to perform
      ShiftRows(). The ShiftRows() transformation cyclically shifts the
      last 3 rows of the state over different offsets. The first row
      (r = 0) is not shifted.

      s'_r,c = s_r,(c + shift(r, Nb) mod Nb
      for 0 < r < 4 and 0 <= c < Nb and
      shift(1, 4) = 1
      shift(2, 4) = 2
      shift(3, 4) = 3.

      This causes the first byte in r = 1 to be moved to the end of
      the row, the first 2 bytes in r = 2 to be moved to the end of
      the row, the first 3 bytes in r = 3 to be moved to the end of
      the row:

      r1: [c0 c1 c2 c3] => [c1 c2 c3 c0]
      r2: [c0 c1 c2 c3]    [c2 c3 c0 c1]
      r3: [c0 c1 c2 c3]    [c3 c0 c1 c2]

      We can make these substitutions inline with our column mixing to
      generate an updated set of equations to produce each word in the
      state (note the columns have changed positions):

      c0 c1 c2 c3 => c0 c1 c2 c3
      c0 c1 c2 c3    c1 c2 c3 c0  (cycled 1 byte)
      c0 c1 c2 c3    c2 c3 c0 c1  (cycled 2 bytes)
      c0 c1 c2 c3    c3 c0 c1 c2  (cycled 3 bytes)

      Therefore:

      c'0 = 2*r0,c0 + 3*r1,c1 + 1*r2,c2 + 1*r3,c3
      c'0 = 1*r0,c0 + 2*r1,c1 + 3*r2,c2 + 1*r3,c3
      c'0 = 1*r0,c0 + 1*r1,c1 + 2*r2,c2 + 3*r3,c3
      c'0 = 3*r0,c0 + 1*r1,c1 + 1*r2,c2 + 2*r3,c3

      c'1 = 2*r0,c1 + 3*r1,c2 + 1*r2,c3 + 1*r3,c0
      c'1 = 1*r0,c1 + 2*r1,c2 + 3*r2,c3 + 1*r3,c0
      c'1 = 1*r0,c1 + 1*r1,c2 + 2*r2,c3 + 3*r3,c0
      c'1 = 3*r0,c1 + 1*r1,c2 + 1*r2,c3 + 2*r3,c0

      ... and so forth for c'2 and c'3. The important distinction is
      that the columns are cycling, with c0 being used with the m0
      map when calculating c0, but c1 being used with the m0 map when
      calculating c1 ... and so forth.

      When performing the inverse we transform the mirror image and
      skip the bottom row, instead of the top one, and move upwards:

      c3 c2 c1 c0 => c0 c3 c2 c1  (cycled 3 bytes) *same as encryption
      c3 c2 c1 c0    c1 c0 c3 c2  (cycled 2 bytes)
      c3 c2 c1 c0    c2 c1 c0 c3  (cycled 1 byte)  *same as encryption
      c3 c2 c1 c0    c3 c2 c1 c0

      If you compare the resulting matrices for ShiftRows()+MixColumns()
      and for InvShiftRows()+InvMixColumns() the 2nd and 4th columns are
      different (in encrypt mode vs. decrypt mode). So in order to use
      the same code to handle both encryption and decryption, we will
      need to do some mapping.

      If in encryption mode we let a=c0, b=c1, c=c2, d=c3, and r<N> be
      a row number in the state, then the resulting matrix in encryption
      mode for applying the above transformations would be:

      r1: a b c d
      r2: b c d a
      r3: c d a b
      r4: d a b c

      If we did the same in decryption mode we would get:

      r1: a d c b
      r2: b a d c
      r3: c b a d
      r4: d c b a

      If instead we swap d and b (set b=c3 and d=c1), then we get:

      r1: a b c d
      r2: d a b c
      r3: c d a b
      r4: b c d a

      Now the 1st and 3rd rows are the same as the encryption matrix. All
      we need to do then to make the mapping exactly the same is to swap
      the 2nd and 4th rows when in decryption mode. To do this without
      having to do it on each iteration, we swapped the 2nd and 4th rows
      in the decryption key schedule. We also have to do the swap above
      when we first pull in the input and when we set the final output. */

/**
 * See NIST SP-800-38D 6.3 (Algorithm 1). This function performs Galois

 *
 * x^128 + x^7 + x^2 + x + 1
 *
 * Which is represented in little-endian binary form as: 11100001 (0xe1). When
 * the value of a coefficient is 1, a bit is set. The value R, is the
 * concatenation of this value and 120 zero bits, yielding a 128-bit value
 * which matches the block size.
 *
 * This function will multiply two elements (vectors of bytes), X and Y, in
 * the field GF(2^128). The result is initialized to zero. For each bit of
 * X (out of 128), x_i, if x_i is set, then the result is multiplied (XOR'd)
 * by the current value of Y. For each bit, the value of Y will be raised by
 * a power of x (multiplied by the polynomial x). This can be achieved by
 * shifting Y once to the right. If the current value of Y, prior to being
 * multiplied by x, has 0 as its LSB, then it is a 127th degree polynomial.
 * Otherwise, we must divide by R after shifting to find the remainder.

  /* Chinese remainder theorem (CRT) states:

    Suppose n1, n2, ..., nk are positive integers which are pairwise
    coprime (n1 and n2 have no common factors other than 1). For any
    integers x1, x2, ..., xk there exists an integer x solving the
    system of simultaneous congruences (where ~= means modularly
    congruent so a ~= b mod n means a mod n = b mod n):

    x ~= x1 mod n1
    x ~= x2 mod n2
    ...
    x ~= xk mod nk

    This system of congruences has a single simultaneous solution x
    between 0 and n - 1. Furthermore, each xk solution and x itself
    is congruent modulo the product n = n1*n2*...*nk.
    So x1 mod n = x2 mod n = xk mod n = x mod n.

    The single simultaneous solution x can be solved with the following
    equation:

    x = sum(xi*ri*si) mod n where ri = n/ni and si = ri^-1 mod ni.

    Where x is less than n, xi = x mod ni.

    For RSA we are only concerned with k = 2. The modulus n = pq, where
    p and q are coprime. The RSA decryption algorithm is:

    y = x^d mod n

    Given the above:

    x1 = x^d mod p
    r1 = n/p = q
    s1 = q^-1 mod p
    x2 = x^d mod q
    r2 = n/q = p
    s2 = p^-1 mod q

    So y = (x1r1s1 + x2r2s2) mod n
         = ((x^d mod p)q(q^-1 mod p) + (x^d mod q)p(p^-1 mod q)) mod n

    According to Fermat's Little Theorem, if the modulus P is prime,
    for any integer A not evenly divisible by P, A^(P-1) ~= 1 mod P.
    Since A is not divisible by P it follows that if:
    N ~= M mod (P - 1), then A^N mod P = A^M mod P. Therefore:

    A^N mod P = A^(M mod (P - 1)) mod P. (The latter takes less effort
    to calculate). In order to calculate x^d mod p more quickly the
    exponent d mod (p - 1) is stored in the RSA private key (the same
    is done for x^d mod q). These values are referred to as dP and dQ
    respectively. Therefore we now have:

    y = ((x^dP mod p)q(q^-1 mod p) + (x^dQ mod q)p(p^-1 mod q)) mod n

    Since we'll be reducing x^dP by modulo p (same for q) we can also
    reduce x by p (and q respectively) before hand. Therefore, let

    xp = ((x mod p)^dP mod p), and
    xq = ((x mod q)^dQ mod q), yielding:

    y = (xp*q*(q^-1 mod p) + xq*p*(p^-1 mod q)) mod n

    This can be further reduced to a simple algorithm that only
    requires 1 inverse (the q inverse is used) to be used and stored.
    The algorithm is called Garner's algorithm. If qInv is the
    inverse of q, we simply calculate:

    y = (qInv*(xp - xq) mod p) * q + xq

    However, there are two further complications. First, we need to
    ensure that xp > xq to prevent signed BigIntegers from being used
    so we add p until this is true (since we will be mod'ing with
    p anyway). Then, there is a known timing attack on algorithms
    using the CRT. To mitigate this risk, "cryptographic blinding"
    should be used. This requires simply generating a random number r
    between 0 and n-1 and its inverse and multiplying x by r^e before
    calculating y and then multiplying y by r^-1 afterwards. Note that
    r must be coprime with n (gcd(r, n) === 1) in order to have an
    inverse.

/**
 * Javascript implementation of Abstract Syntax Notation Number One.
 *
 * @author Dave Longley
 *
 * Copyright (c) 2010-2015 Digital Bazaar, Inc.
 *
 * An API for storing data using the Abstract Syntax Notation Number One
 * format using DER (Distinguished Encoding Rules) encoding. This encoding is
 * commonly used to store data for PKI, i.e. X.509 Certificates, and this
 * implementation exists for that purpose.
 *
 * Abstract Syntax Notation Number One (ASN.1) is used to define the abstract
 * syntax of information without restricting the way the information is encoded
 * for transmission. It provides a standard that allows for open systems
 * communication. ASN.1 defines the syntax of information data and a number of
 * simple data types as well as a notation for describing them and specifying
 * values for them.
 *
 * The RSA algorithm creates public and private keys that are often stored in
 * X.509 or PKCS#X formats -- which use ASN.1 (encoded in DER format). This
 * class provides the most basic functionality required to store and load DSA
 * keys that are encoded according to ASN.1.
 *
 * The most common binary encodings for ASN.1 are BER (Basic Encoding Rules)
 * and DER (Distinguished Encoding Rules). DER is just a subset of BER that
 * has stricter requirements for how data must be encoded.
 *
 * Each ASN.1 structure has a tag (a byte identifying the ASN.1 structure type)
 * and a byte array for the value of this ASN1 structure which may be data or a
 * list of ASN.1 structures.
 *
 * Each ASN.1 structure using BER is (Tag-Length-Value):
 *
 * | byte 0 | bytes X | bytes Y |
 * |--------|---------|----------
 * |  tag   | length  |  value  |
 *
 * ASN.1 allows for tags to be of "High-tag-number form" which allows a tag to
 * be two or more octets, but that is not supported by this class. A tag is
 * only 1 byte. Bits 1-5 give the tag number (ie the data type within a
 * particular 'class'), 6 indicates whether or not the ASN.1 value is
 * constructed from other ASN.1 values, and bits 7 and 8 give the 'class'. If
 * bits 7 and 8 are both zero, the class is UNIVERSAL. If only bit 7 is set,
 * then the class is APPLICATION. If only bit 8 is set, then the class is
 * CONTEXT_SPECIFIC. If both bits 7 and 8 are set, then the class is PRIVATE.
 * The tag numbers for the data types for the class UNIVERSAL are listed below:
 *
 * UNIVERSAL 0 Reserved for use by the encoding rules
 * UNIVERSAL 1 Boolean type
 * UNIVERSAL 2 Integer type
 * UNIVERSAL 3 Bitstring type
 * UNIVERSAL 4 Octetstring type
 * UNIVERSAL 5 Null type
 * UNIVERSAL 6 Object identifier type
 * UNIVERSAL 7 Object descriptor type
 * UNIVERSAL 8 External type and Instance-of type
 * UNIVERSAL 9 Real type
 * UNIVERSAL 10 Enumerated type
 * UNIVERSAL 11 Embedded-pdv type
 * UNIVERSAL 12 UTF8String type
 * UNIVERSAL 13 Relative object identifier type
 * UNIVERSAL 14-15 Reserved for future editions
 * UNIVERSAL 16 Sequence and Sequence-of types
 * UNIVERSAL 17 Set and Set-of types
 * UNIVERSAL 18-22, 25-30 Character string types
 * UNIVERSAL 23-24 Time types
 *
 * The length of an ASN.1 structure is specified after the tag identifier.
 * There is a definite form and an indefinite form. The indefinite form may
 * be used if the encoding is constructed and not all immediately available.
 * The indefinite form is encoded using a length byte with only the 8th bit
 * set. The end of the constructed object is marked using end-of-contents
 * octets (two zero bytes).
 *
 * The definite form looks like this:
 *
 * The length may take up 1 or more bytes, it depends on the length of the
 * value of the ASN.1 structure. DER encoding requires that if the ASN.1
 * structure has a value that has a length greater than 127, more than 1 byte
 * will be used to store its length, otherwise just one byte will be used.
 * This is strict.
 *
 * In the case that the length of the ASN.1 value is less than 127, 1 octet
 * (byte) is used to store the "short form" length. The 8th bit has a value of
 * 0 indicating the length is "short form" and not "long form" and bits 7-1
 * give the length of the data. (The 8th bit is the left-most, most significant
 * bit: also known as big endian or network format).
 *
 * In the case that the length of the ASN.1 value is greater than 127, 2 to
 * 127 octets (bytes) are used to store the "long form" length. The first
 * byte's 8th bit is set to 1 to indicate the length is "long form." Bits 7-1
 * give the number of additional octets. All following octets are in base 256
 * with the most significant digit first (typical big-endian binary unsigned
 * integer storage). So, for instance, if the length of a value was 257, the
 * first byte would be set to:
 *
 * 10000010 = 130 = 0x82.
 *
 * This indicates there are 2 octets (base 256) for the length. The second and
 * third bytes (the octets just mentioned) would store the length in base 256:
 *
 * octet 2: 00000001 = 1 * 256^1 = 256
 * octet 3: 00000001 = 1 * 256^0 = 1
 * total = 257
 *
 * The algorithm for converting a js integer value of 257 to base-256 is:
 *
 * var value = 257;
 * var bytes = [];
 * bytes[0] = (value >>> 8) & 0xFF; // most significant byte first
 * bytes[1] = value & 0xFF;        // least significant byte last
 *
 * On the ASN.1 UNIVERSAL Object Identifier (OID) type:
 *
 * An OID can be written like: "value1.value2.value3...valueN"
 *
 * The DER encoding rules:
 *
 * The first byte has the value 40 * value1 + value2.
 * The following bytes, if any, encode the remaining values. Each value is
 * encoded in base 128, most significant digit first (big endian), with as
 * few digits as possible, and the most significant bit of each byte set
 * to 1 except the last in each value's encoding. For example: Given the
 * OID "1.2.840.113549", its DER encoding is (remember each byte except the
 * last one in each encoding is OR'd with 0x80):
 *
 * byte 1: 40 * 1 + 2 = 42 = 0x2A.
 * bytes 2-3: 128 * 6 + 72 = 840 = 6 72 = 6 72 = 0x0648 = 0x8648
 * bytes 4-6: 16384 * 6 + 128 * 119 + 13 = 6 119 13 = 0x06770D = 0x86F70D
 *
 * The final value is: 0x2A864886F70D.
 * The full OID (including ASN.1 tag and length of 6 bytes) is:
 * 0x06062A864886F70D
