sumTwoMonomials -- tally the sequences of BRanks for certain examples

tallies the sequences of B-ranks that occur for sums of pairs of monomials in R = S/(d-th powers of the variables), with full complexity (=c); that is, for an appropriate syzygy M of M0 = R/(m1+m2) where m1 and m2 are monomials of the same degree.
