This was an experiment to use the BDD checker's ability to generate the set of all backwards-reachable states to try and come up with an invariant that would hold for any sort sizes. It currently works for
lockserver, but the BDD checker is too slow to test it on longer examples. (Also, the current invariant inference part of the implementation can only generateforallinvariants.)
