python 3.x compatibility

[embodyhumility]

Is anyone using python 3 with this successfully?

@embodyhumility I dont think so. I am not super familiar with python 3 but it seems like there were some changes with how you do imports that would keep this from being compatible. I have a branch where I have tried building and testing on python 3 with travis-ci and it fails.
