| class | CutPool |
Class for communication between CutPool and LinearRelax.
Adding a cut, returnes a CutInfo, so the linear relaxation can remember a cut, which is added to it. Solving the linear relaxation sets the inactive flag. This is checked by update_nodeinfo, which sets the removed flag. This flag can be checked by LinearRelax again.
