[EM] Request for proposed methods

It looks like there isn't any wiki page for Double Defeat, Hare.

For methods like that and Margins Sorted Approval in public elections, I 
think it is highly desirable that the approval cutoffs should be as 
explicit and "manual" as possible.  So for example I'm not entirely 
comfortable with the idea of using say 6-slot ratings ballots and saying 
we'll just "interpret" the top 3 slots as signifying approval.

Also I'm not enthusiastic about allowing above-bottom equal-ranking in 
Hare, Benham or Double Defeat, Hare.  But if people insist on it, I 
favour using the fractional approach to initially order the candidates 
(so a ballot that ranks, among remaining candidates, equal-top 
preference to more than one candidate gives equal fractions of a vote, 
summing to 1, to each candidate) and then have ballots that equal-top 
rank more than one candidate give a whole single vote to the candidate 
highest in that initial fractional order.
Then if more than one candidate remains (and we have no winner) 
eliminate the candidate with the fewest  top (among remaining 
candidates) whole votes.

But complicated and messy. Just tell the voters they have to strictly 
rank (with truncation allowed) and ballots that equal-rank are just 
counted as having truncated at that rank.
