Fix failing test in travis-ci add tox.ini for local testing

The last commit changed a feature without updating the test, so is
failing in travis ci. This fixes that issue, as well as adding a
tox.ini file for easy local testing. Tox is a pretty standard test run
setup tool for python projects, and makes it easy to test against
multiple python versions simultaneously. The added one is boiler plate
for python 2.7, 3.4 -> 3.6, and has a pep8 rule.
