[Nauty] isomorphism between 2 graphs

[Wahid Chrabakh]

Hi:
	I am a new user of nauty. I want to write a small function which will
	take as input two graphs and output if the two graphs are isomorphic.
	I looked through the documentation but could not figure out how to do
	this.
	Does such function already exist? Does anyone know of such sample
	code? Or can you just give me suggestions where to start?

	thanks,
	Wahid.
