Updated Sphinx Documentation

Hi,

I finally got some time to update the sphinx documentation. The final result is at [1] and the git repo can be cloned from [2]. Basically, so far I've just pulled stuff from the google pages and converted into sphinx format and did some polishing. I think it's a good start, but definitely needs more work! For example, the tutorial right now is more "theoretical", and may not be "practical" enough for a new user to understand...probably this can be separated into a simpler tutorial and then an advanced tutorial or reference section, especially the problem description format.

Also, I haven't had time to look into genDocs.py yet...

Thanks! Logan
