Griso

Griso is a graph isomorphism testing utility written in C++. It is based on my own POLYNOMIAL-TIME (in this point the salt of the project) algorithm. See Griso's sample input/output on http://funkybee.narod.ru/graphs.htm page. Edit (2012-10-24): seems so far it works for *regular graphs only* and should be tested on such graphs. Edit (2012-10-25): see two counterexamples in README.txt. But yet if Griso's verdict is "NON-isomorphic" it's 100% correct, so you can still make use of it. PS: on the above link all answers are correct.
