[SCIP] Restart SCIP

[Benjamin Müller]

Dear Samuel,

after you called SCIPsolve() you need to free the transformed problem 
via SCIPfreeTransform(). Afterwards you can add new constraints as you 
have done it before with SCIPaddCons(), and removing existing ones with 
SCIPdelCons().

Note that SCIP checks whether some of the previously found feasible 
solutions are still feasible for the new problem. This requires that you 
don't create your problem from scratch (i.e. calling SCIPfree() and then 
SCIPcreate() again), but rather use the functions mentioned above.

Regards,
Benjamin
