Enhance Functions to get Class information from files (using AST )

[Stephanevg]

I would like to update the following functions to not only show 'only loaded' classes, but also get the same class information from a class located in a file.

The following functions should be enhanced:

• [x] Get-CUClass
• [x] Get-CUClassConstructor
• [x] Get-CUClassMethod
• [x] Get-CUClassProperty

These are the technical details I think this could work at best:

Add Parameter: -Path

• [x] Possibility to read class from .PSM1 file
• [x] Possibility to read class from .PS1 file
• [ ] Should Throw if not of type [System.IO.FileInfo]
• [ ] Should throw if doesn't have extension .psm1 or .ps1

I think the best and easiest way for that, would be to add a call to Get-CUAST in each of these functions, and add some filtering. This could also mean, that by extension, Get-CUAST might need some need options - Will see.

We have taken another design approaoch, where Get-CUClass will be main entry point.
