// Description...: Creates the discernibility function from the
//                 given non-NULL discernibility matrix entries.
//
//                 Simplifies the function if specified.
//
// Comments......: Non-public method, for internal use.
//
//                 The weight vector should have been properly
//                 initialized, if present.
//
//                 The non-NULL entries should be from a matrix of
//                 representatives, if simplification is specified.
