OsiRowCut augmented with bookkeeping.
CbcCountRowCut is an OsiRowCut object augmented with bookkeeping information: a reference count and information that specifies the the generator that created the cut and the node to which it's associated.
The general principles for handling the reference count are as follows:
When all possible uses of a cut have been demonstrated to be unnecessary, the reference count (numberPointingToThis_) will fall to zero. The CbcCountRowCut object (and its included OsiRowCut object) are then deleted.

Set the information associating this cut with a node.
An CbcNodeInfo object and an index in the cut set of the node. For locally valid cuts, the node will be the search tree node where the cut was generated. For globally valid cuts, it's the node where the cut was activated.
