Generalized MPI size and formed relation bug fix

-Formed relations were increasing because some agents were forming
multiple relationships in a single round -- a check has been added to
keep this from happening.
-Also agents were graduating to the next gq regardless of their network
degree -- a check has been added for this as well.
