Currently, the logical iff operator <==> is not supported. This previously wasn't a problem as WyC translated this into disjunctions for us. But, the latest version of WyC supports <==> all the way through. A simple example:

    forall(int x):
        (x > 0) <==> (x > 0)

Add Support for Logical IFF #137
This adds support for breaking down the logical iff operator into a
union of two conjuncts.  Here, a <==> b becomes (a&&b)||(!a&&!b).

Most of the machinery for dealing with the iff operator was already in
place.  For example, it was already being parsed etc.
