Expand description

main procedure of the proximity heuristic, creates and solves a sub-SCIP

@note the method can be applied in an iterative way, keeping the same subscip in between. If the @p freesubscip parameter is set to FALSE, the heuristic will keep the subscip data structures. Always set this parameter to TRUE, or call SCIPdeleteSubproblemProximity() afterwards
