Initial commit.
Debugged with Arnold Tharrington, 11/19/2012
Added establishGroups subroutine. Hasn't been debugged yet.
After initial debugging with Arnold. Still not functioning.
Mostly finished. Broadcasts are causing errors.
Issue does not appear to be with creation of either
 groups or communicators.
Should be finally finished!
First stage of making code modular. Made matrix size read in from file.
Just joking about the last commit. THIS is the proper code which is
my initial "variable size" array code.
