00009 /*  There are cases where the user wants to control how CBC sees the problems feasibility.
00010     The user may want to examine the problem and say :
00011     a) The default looks OK
00012     b) Pretend this problem is Integer feasible
00013     c) Pretend this problem is infeasible even though it looks feasible
00014 
00015     This simple class allows user to do that.
