Corrected cloning and initialization problem.
Adding booleans for checking more precisely for potential mappings. When checking available operators for an actor, a scheduling heuristic can choose to take into account, or not, the mapping of the other elements in the group.
Modified getCandidateOperators and map functions
to fit the new policies for relativeConstraints.
Corrected a small bug on remapping.
Close to working with FAST. Still some groups mapped to
different operators causing loops in the DAG.
Corrected the problem on FAST.
Cleaning the code after debug.
