Extending a Region to create a JUNG Layout

[Jeffrey Guenther]

Danno, thanks! It works super well and has so little code!

If I use the class in my JUNG work, I need a BSD license. The rest of that codebase is BSD already. I’ll contact you off list if I go that direction. Right now, I’m trying to get my head wrapped around what it would take to modernize JUNG.
