8/*  There are cases where the user wants to control how CBC sees the problems feasibility.
9    The user may want to examine the problem and say :
10    a) The default looks OK
11    b) Pretend this problem is Integer feasible
12    c) Pretend this problem is infeasible even though it looks feasible
13   
14    This simple class allows user to do that.
