No Py3 support and not support PEP8？

Thanks for the advice.

1. We stick to py2 currently.
2. We will do the code clean ASAP. Or you may also help on it :)

@xiaoxq
for the 1st issue,it's a pity/(ㄒoㄒ)/~~ mainly because I don't find some gevent-like-python2-only-library in use,so I just think compatibility with python3 won't be very difficult？(⊙﹏⊙) even Tensorflow supports both version,so......～～
and the 2nd,thanks for your appreciation～~Now I'll try to see how C++ code is writen,Python is just a wrapper and plot toolkit :)
