- Renamed 'TopRow' to 'StartRow' and added alias
(More concise with future parameter names like 'StartColumn')
- Removed 'ChangeList' in 'Notes' as this is tracked in Git
- Added parameter 'Password' to import password protected files
- Added Pester tests for parameter aliasses and:
- parameter 'Password'
- parameter 'Path' validation for extensions '.xls' and '.xlsx'
- 'HeaderName' witb blanks
- Changed comments in Pester tests from '<# Comment #>' to '# Comment'
(Easier to outcomment a whole block of tests when performing a test on a specific piece of code)
