.DESCRIPTION
    To take a normal Windows path and convert it to a bash path for things like git bash.
.PARAMETER Path
    A path to a file or files. Can include wildcards and the wildcards will be resolved to underlying

.PARAMETER IncludeInput
    Switch to indicate if input parameters should be included in the output, aliased to 'IncludeOriginal'
.PARAMETER NoResolvePath
    Switch to not resolve the provided path to see if it exists
.EXAMPLE
    Get-BashPath -Path 'c:\temp\*.csv'

    /C/temp/Encoding\ Time.csv
.EXAMPLE
    Get-BashPath -Path 'c:\temp\*.csv' -IncludeInput

    Posh                      bash
    ----                      ----
    C:\temp\Encoding Time.csv /C/temp/Encoding\ Time.csv
.EXAMPLE
    $Special = Show-SpecialFolder -IncludeLocations | Where-Object {$_.Location -and $_.Location -match 'Program Files'}
    $Special | Add-Member -MemberType NoteProperty -Name BashPath -Value 'x'
    foreach ($s in $special) { $s.BashPath = Get-BashPath -Path $s.Location }
    $Special

    Would return
    SpecialFolder         Location                            BashPath
