 Lab Manager VM NAT Getter
=============================================================================================
 Simon Strutt  -  November 2010
=============================================================================================

Version 1
 - Initial creation!
 
Version 1.1 - Dec 2010
 - Added bucketName when displaying list of config's to better handle config's with same name in different workspaces
 
Version 1.2 - Jan 2011
 - Added sorting by VM name
 
Version 1.3 - Feb 2011
 - Configuration selection menu...
 -- Now sorted by name
 -- Displays configs in yellow if they're not shared
 
Version 2.0 - Apr 2011
 - Changed from single run to modular, continuous operation
 - Added RDP port test
