[EM] Cloneproof Schwartz Sequential Dropping / Schulze

[Markus Schulze]

Dear James Green-Armytage,

Example:

   A:B=50:50
   A:C=50:50
   A:D=50:50
   B:C=75:25
   B:D=40:60
   C:D=65:35

SSD would declare A the winner since he is the only candidate
who isn't beaten by anybody.

CSSD would drop B:D to get rid of the B>C>D>B cycle.
And then it would report a tie between A and B.

You can also find an old description of CSSD here:
