To clarify, MMCWPO is MinMax (MMPO) combined with James
Green-Armytage's Cardinal Weighted Pairwise method.
That is, one accumulates two pairwise matrices.
The first is the standard pairwise array, with position (A, B)
containing the number of ballots ranking A over B.
The second array stores cardinal weighted preferences: in those cases
where a ballot prefers candidate A to candidate B, save A-score minus
B-score into position (A, B).
Applying this to MMPO: instead of using winning votes, determine the
pairwise opposition for a defeat by the CW(A,B) score-difference sum
instead of P(A,B) winning votes.
