.Synopsis
   Opens a new RDP connection to a specified computer using the given credentials.
.DESCRIPTION
   Give this thing an array of computer names and a credential to connect to them on and it will open up an RDP session and log you into all of them. 
   This is great for when you have a huge list of computers that you need to remote into. 
.EXAMPLE
   $cred = get-credential
   $ListOfComputerNames = "Server1","Server2","Server3"
   $ListOfComputerNames | Connect-RDPComputers -Credential $cred

   In this example, I supply a credential object and an array of computer names.
   I then pipe the computer names into Connect-RDPComputers and it will open an RDP session for each computer and log me into each of them with the given credential.
