Moved the code to print Venn Diagram commands to a subfunction
Added subfunction to list items in each set

This is working funky, and I'm going to try a bit of a rewrite to fix it, but I'm
committing now to allow a roll-back if necessary
Finally tracked down the problem with this script. The GetGroups function is now working
but I commented it out and restored the original functionality of producing the commands
for a Venn diagram.

Ideally I would code a command line switch, but I don't know how often it will be needed
