The Travis instance for this repo needs to be upgraded

[cclauss]

The Travis instance has old versions of pip, Python 2, and Python 3. It has no ability to test Python 3.5 and 3.6. See #339

Travis doesn't so much need to be updated as much as we just need to tell travis to provide us with newer interpreters. See #341

Well done! Now I understand.
