update model (This is needed if cliques update matrix etc)

Reimplemented from CbcHeuristic.

virtual int CbcHeuristicCrossover::solution	(	double &	objectiveValue,
		double *	newSolution
	)			[virtual]

returns 0 if no solution, 1 if valid solution.

Fix variables if agree in useNumber_ solutions when_ 0 off, 1 only at new solutions, 2 also every now and then add 10 to make only if agree at lower bound

Implements CbcHeuristic.
