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

    !!IMPORTANT SECURITY NOTE!!
 
    This module will set trusted hosts to connect to any machine on the local network.
    This is NOT a recommended security practice. It is assumed you are installing this
    module on a non-production machine and are willing to accept this potential risk
    for the sake of a training and test environment.
