[boost] [Boost][BGL] New isomorphism test algorithm contribution

Hi, I have been developing a new implementation for test graphs isomorphism, named conauto <http://sites.google.com/site/giconauto/> algorithm (based on José Luis López Presa thesis). I would like to contribute it to BGL. This is a more efficient algorithm than the current one. You can study all its details from conauto thesis at here<http://www.diatel.upm.es/jllopez/tesis/thesis.pdf> . Once developed the first conauto BGL-style version, I am sure that there are many advises and comments that could help to enhance it and eventually will be acceptable for BGL maintainers. Find attached both the source code and some measurements graphics. Please, do not hesitate ask me for any additional information. Best regards, Carlos Cardeñosa.
