Title: Physics doctests/strings

For task http://www.google-melange.com/gci/task/view/google/gci2011/7233307.

Asmeurer and I couldn't find someone to explain some of the functions in secondquant so the functions and classes deriving from FockState do not have documentation. There is also a printing bug because of the way FockState is printed which means that any doctests I would add would be simple equal methods, not too helpful in my opinion.
