    Function Get-NormalizedFileSystemPath {
        <#
        .Synopsis
            Normalizes file system paths.
        .DESCRIPTION
            Normalizes file system paths.  This is similar to what the Resolve-Path cmdlet does, except Get-NormalizedFileSystemPath also properly handles UNC paths and converts 8.3 short names to long paths.
        .PARAMETER Path
            The path or paths to be normalized.
        .PARAMETER IncludeProviderPrefix
            If this switch is passed, normalized paths will be prefixed with 'FileSystem::'.  This allows them to be reliably passed to cmdlets such as Get-Content, Get-Item, etc, regardless of Powershell's current location.
        .EXAMPLE
            Get-NormalizedFileSystemPath -Path '\\server\share\.\SomeFolder\..\SomeOtherFolder\File.txt'

            Returns '\\server\share\SomeOtherFolder\File.txt'
        .EXAMPLE
            '\\server\c$\.\SomeFolder\..\PROGRA~1' | Get-NormalizedFileSystemPath -IncludeProviderPrefix

            Assuming you can access the c$ share on \\server, and PROGRA~1 is the short name for "Program Files" (which is common), returns:

            'FileSystem::\\server\c$\Program Files'
        .INPUTS
            String
