The symbolic values of this enumeration specify how CPLEX
manages cuts added by the user.
UseCutForce: The cut is added and never removed.
UseCutPurge:
The cut is added, but CPLEX may purge (eliminate) the cut later.
UseCutFilter:
The cut is treated exactly as other cuts added by CPLEX.
That is, CPLEX applies its filtering process to the cut.
As a consequence of the filtering process, CPLEX may decide
not to add the cut to the relaxation, for example, if CPLEX
deems other cuts more effective, or if the cut is too dense,
or other possible filtering criteria).
