    .SYNOPSIS
    Returns $obj as indented string

    .DESCRIPTION
    Turns $obj to string and adds $indent * 4 spaces in front of it

    .PARAMETER obj
    Object to be converted to String

    .PARAMETER indent
    How many whitespaces * 4 to indent

    .EXAMPLE
    Get-IdentedString "Test" 1
    >>> "    Test"

Export-ModuleMember Export-PowerShellDataFile

I attempted to pass this along: $obj = [PsCustomObject]@{Name='file'}. It could not process that object. I tried with a hash table and it worked. I am recasting it a bit into a different module. Instead of using Export-ModuleMember, I put it in the "public" subfolder of my module apparatus. I then dot then entire script as a function.
