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.
which_ points directly to columns of matrix

Constructor & Destructor Documentation
| CbcSOS::CbcSOS | ( | ) |
| CbcSOS::CbcSOS | ( | CbcModel * | model, | |
| int | numberMembers, | |||
| const int * | which, | |||
| const double * | weights, | |||
| int | identifier, | |||

Useful constructor - which are indices and weights are also given.
If null then 0,1,2.. type is SOS type
