ternary operator vote

[Andrew Koenig]

Bengt> +1 if you allow the votes to be from {-1, -0, +0, +1} with
Bengt> abstention as 0.

Please read http://www.electionmethods.org/approved.htm which, among
other things, explains why voting "yes" or "no" for each of the
alternatives is better than allowing a continuum of values.
