 	.DESCRIPTION
 		Parses a module that uses the PSFramework localization feature for strings and their value.

+
 	.PARAMETER ModuleRoot
 		The root of the module to process.
 		Must be the root folder where the psd1 file is stored in.
-	
+
 	.EXAMPLE
 		PS C:\> Export-PSMDString -ModuleRoot 'C:\Code\Github\MyModuleProject\MyModule'
