Detailed Description
Define Special Ordered Sets of type 1 and 2.
These do not have to be integer - so do not appear in lists of integers.

| virtual double OsiSOS::feasibleRegion | ( | OsiSolverInterface * | solver, | |

Set bounds to fix the variable at the current (integer) value.
Given an integer value, set the lower and upper bounds to fix the variable. Returns amount it had to move variable.
