Python3 roadmap

[brennv]

Continuing the discussion from #15. I think adding travis and getting tests passing would good start. That way we can watch follow-on PRs pass or fail.

• [x] fix tests #20
• [x] add travis #11
• [x] fix spacing #25
• [x] clean up #27
• [x] add Python 3 support #28
• [x] maybe more pep8 fun #29 and/or refactor tests
• [x] update readme #30 and bump version #31
• [ ] pypi release
