  Log Message:
  -----------
  Fix the typegetter _prefix tables to use bytes.

Add test cases for this.

Also consistently pass bytes from the test case.

Fixes #6.

I ran into the namespace package issue ("can't import zope.interface")
when testing with tox using 'setup.py test' so I switched the runners
to zope.testrunner, which seems to have solved the problem.

I took this opportunity to enable coverage reports as well as pip
caching, and added Python 3.6 to the support list.
