The library has now been tested with Python 2.7, 3.3, 3.4, 3.5, and 3.6.
The README and setup.py now indicate this.  The README also says how to
run the tests, and that you need a PD Buddy Sink plugged in for them to
be completely thorough.

May change before the real 0.1 release, but this allows easier test
coverage measurements.
