[EM] PR Condorcet algorithm implemented as experiment

[Andrew Myers]

I implemented the PR-enforcing Condorcet algorithm I described in my recent
mail to this list, as part of the CIVS voting web service.  If you would like
to try it out (and give me some testing!), visit the following URL and vote on
the "ice cream assortment" election:

You can of course set up your own elections using this system too.

Cheers,
