Forcing Synchronization of Display Name and Email from Active Directory without User Profile Synchronization - PowerShell Script

Just made this script to Synchronize Display Name and Email for all users in a root web if they have been updated in AD and aren't flowing through to your display name in SharePoint. This may be required if the user profile service is not set up or is failing. This problem is discussed in more detail at https://gallery.technet.microsoft.com/office/User-Information-List-in-8b420e8c
