       .SYNOPSIS
         Applies Number, font, alignment and colour formatting to a range of Excel Cells
+      .DESCRIPTION
+        Set-Format was created to set the style elements for a range of cells, this includes autosizing and hiding, setting
+        font elements (Name, Size, Bold, Italic, Underline & UnderlineStyle and Subscript & SuperScript), font and background colors,
+        borders, text wrapping, rotation, aliginment within cells, and number format.
+        It has been extended to set Values, Formulas and set ArrayFormulas (sometimes called Ctrl-shift-Enter [CSE] formulas); because of this
+        it has an alias of Set-ExcelRange - in the future the Alias and Canonical name may swapped.
