[EM] suggestion for Approval/Pairwise method

[Russ Paielli]

I'm up too late again, and I just had an interesting idea. If the 
following method has been proposed before, please let me know.

The voters rank the candidates and specify an Approval cutoff. The 
winner is then the pairwise winner of the top-two most-approved candidates.

If it doesn't have a name already, let me tentatively call it ATTPR for 
Approval Top-Two Pairwise Runoff.

A simpler variation would be to let the voter rank only the approved 
candidates, thereby eliminating the need for an explicit Approval cutoff.

Good night, or good morning, whichever the case may be.
