1. FP score function
2. FP evaluator (partially done)
3. Fix parser (BV constants, conversions to core language, etc.)
4. Try Z3 SLS and compare performance
5. Try FP->BV on Z3 SLS
6. add tests to submodule
7. add types to score functions (they should be rational rather than floating point)
- SLS heuristics in the original paper
