SetupTearDown.ps1

<#
.SYNOPSIS
    Set up (or clean up) PSRemoting on this computer. Setup up option will Enable-PSRemoting and setup the machine to be able to run ps commands programmatically
    Cleanup up option will Disable-PSRemoting and perform other tasks that were done during setup like disable WinRM service, delete remoting specific firewall rules, etc.

.PARAMETER Setup
    This Switch will trigger the setup calls which ends up enabling PS Remoting (and which in turn starts the WinRM service and opens up remoting via the firewall

.PARAMETER Cleanup
    This switch triggers the cleanup path which disables WinRM service, removes the firewall rules that were created earlier for remoting, and also Disables PSRemoting

.DESCRIPTION
    Run this script to setup your machine for PS Remoting so that you can leverage the functionality of runPerfTool.psm1
    Run this script at the end of the tool runs to restore state on the machines.
    Ex: SetupTearDown.ps1 -Setup or SetupTearDown.ps1 -Cleanup
