Sphinx doc

Hi, 
Check my ready cool documentation:

http://python-nvd3o.readthedocs.org/en/sphinx_doc/index.html 

Live graphs everywhere. Would allows future users to know exactly what kind of awesome library they are 
getting. 

Man, I know it's a huge PR. I worked on it a lot, considering everything we talked about. It merges smoothly. 
Please remove your sphinx_doc branch, it's not needed anymore.

Cheers, 
Oz
