Revision: 1204

Log Message:
-----------
FFSolver rewrite: disjunctions. FFSolver-FFTNF interface: free variables fixes. FFTNF: Proper subtask handling (a subtask is a ground universally quantified subformula). Tests: executable checking moved to Aux. Solver: exposing more capabilities. Heuristic: abstracting over solver when possible.
