<#
  .Synopis
    Unrolls an object with many sub-objects.
  .Example
    C:> Get-Process -id $PID | Expand-PropertyTree   | ft -a Path,value
    Outputs the paths and values for the unrolled properties for a process object and displays path and value as a table.
    By default the modules and threads properties are limited to showing on 2 of their many members
    We can use -MaxArrayItems to get a different number  0 won't expand at all, and a negative number will expand ALL of them.

<#
.Synopsis
   Signs a script 
.DESCRIPTION
   Gets a users code signing certificate, (if there is just one in "Cert:\CurrentUser\My" it will be selected automatically)  
   and uses it to sign a script file using a timestamping service.
   Without the Time Stamp (Comodo CA is used by default) the signature is only valid for the range of dates on the certificate  
   If -passthrough is specified, retuns the certificate object 
   Else, if -quiet is specified doesn't reurn anything
   Otherwise outputs the detail of the signature

#experimental response to https://github.com/PowerShell/PowerShell/issues/20750
function TabExpansion2 {    
    <# Options include:
        RelativeFilePaths - [bool]
            Always resolve file paths using Resolve-Path -Relative.
            The default is to use some heuristics to guess if relative or absolute is better.

    To customize your own custom options, pass a hashtable to CompleteInput, e.g.
            return [System.Management.Automation.CommandCompletion]::CompleteInput($inputScript, $cursorColumn,
                @{ RelativeFilePaths=$false }
