Clear all row cuts without deleting them.
Handy in case one wants to use CGL without managing cuts in one of the OSI containers. Client is ultimately responsible for deleting the data structures holding the row cuts.

Selective delete and clear for row cuts.
Deletes the cuts specified in to_erase
then clears remaining cuts without deleting them. A hybrid of eraseRowCut(int) and dumpCuts(). Client is ultimately responsible for deleting the data structures for row cuts not specified in to_erase
.
