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