[Couenne] Changing on Couenne code to save information

[Stefan Vigerske]

Hi,

I'm adding a primal heuristic to Couenne in order to track such information.

CouenneSetup couenne_setup;
couenne_setup.heuristics().push_back(BabSetupBase::HeuristicMethod());
couenne_setup.heuristics().back().heuristic = new 
GamsCbcHeurSolveTrace(...);
couenne_setup.heuristics().back().id = "Solvetrace writing heuristic";
