GRBModel.getSOS()

Retrieve the list of variables that participate in an SOS constraint, and the associated coefficients. The return value is the length of this list. Note that the argument arrays must be long enough to accomodate the result. Call the method with null array arguments to determine the appropriate array lengths.
