both Python 2 and Python 3, removing the need for 2to3 to be run. This
indirectly fixes #177.
* Corrected a duplicate-named method in the unit testing code. Corrected the
now-exposed broken logic that wasn't being tested. This was
highlighted in #186 but the author did not appear to realise that the
method name was being masked in the unit test class.
* Corrected the test case skipping logic to use unittest.skipIf instead
of just returning from the method upon an ImportError so that the skip
can actually be registered as a skipped test instead of a passed test.
* Updated the tests to additionally run on Python 3.5 on Travis. This
covers #195.
* Merged the two benchmarking files into one, and modularised the code.
Also added native RST output so the benchmarking results can be placed
directly into the README file.
