[EM] Range Voting fails IIA

[MIKE OSSIPOFF]

IIAC:

Deleting a nonwinning candidate from the ballots, and then recounting those 
ballots should never change who wins.

(end of IIAC definition|

RV and Approval pass IIAC.

The above IIAC definition is the only complete and precise one that I've 
seen. Yes, lots of people invoke an IIAC that is about preferences, but no 
one defines it. Sorry, but an undefined criterion isn't useful.
