Added support for a few versions of Python 3 (3.3–3.5) while retaining Python 2.7 support using the future package.
Tested by adding a Travis CI configuration that tests installation and running tests for Python 2.7 and 3.3–3.5 (with visual output of the build status on the README page rendered in GitHub).
