[EM] MAS is Bucklin (thanks Nevin)

As Nevin Brackett-Rozinsky recently pointed out, the only difference
between MAS and a rated Bucklin (that is, top median, with tiebreaker)
system is that MAS doesn't explicitly state that a candidate with a
majority of top-votes (2's) cannot be beaten by one without such a
majority. Of course, in the real world, that rule would be highly unlikely
to ever have any impact. If one candidate gets over 50% top-ratings, there
is very little chance that there's another candidate who's even close to
them in total score, let alone one who beats them.

Still, I think Nevin's is a useful insight, because it helps tie MAS to the
history of Bucklin as used in the Progressive-era US. One of the first
criticisms MAS will get is that it's a recent innovation, and it needs a
"track record". Saying that "it's just a form of Bucklin, and thus closely
related to voting systems that were used in over a dozen US cities" is a
decent comeback.

fixed things up to show this link.
