method has all heuristic callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeHeurBasic() and setter functions if you seek for a method which is less likely to change in future releases
Returns
SCIP_OKAY is returned if everything worked. otherwise a suitable error code is passed. see SCIP_RETCODE for a complete list of error codes.
Precondition
