- Simplified refutation process: it now collects all the constraints in a given path and, only when it reaches the root node, the refutation manager is created and the constraints are checked for reachability. All the optimizations were removed.
- Moved RangedConstraintManager.h to include/
- Moved refutation check to be the first in the list of BugVisitors
- Added dump method to Z3Solver (to print the formula)
- Added more documentation/comments
