		SYM_GRAPH *	G1,
		SYM_GRAPH *	G2,
		int *	nnodes,

	)

returns whether two given graphs are identical

Parameters

scip	SCIP pointer
sassygraph	pointer to hold sassy graph being created
G1	first graph
G2	second graph
nnodes	pointer to store number of nodes in sassy graph
nnodesfromG1	pointer to store number of nodes in sassy graph arising from G1
success	pointer to store whether sassygraph could be built
