Support for relative input and output file paths

[iRon7]

Currently the Edit-DTWBeautifyScript cmdlet doesn't support relative file paths. As I sometimes have quite long paths to deal with, I would like to be able refer to the input and output file as:

Edit-DTWBeautifyScript .\MySript.ps1 .\MySriptNew.ps1

Which is also common for cmdlets like Get-Content .\MyFile.txt.
