    This is the Setup-Host script. This script will perform the following:
    * For PowerShell Remoting, Set the host 'TrustedHosts' value to *
    * Install the Lability module from PSGallery
    * Install Hyper-V
    * Create the $DestinationPath folder (DO NOT DELETE)
    * Copy configurations and resources to $DestinationPath
    * You will then need to reboot the host before continuing

    Note! - You may delete the folder $SourcePath when this setup finished and the system
            has been rebooted.
