Python Unit Testing Tutorial (PyMOTW unittest update)

tl;dr: an update to PyMOTW for `unittest` in Python 3: Python Unit Testing Tutorial.

When I was learning programming in Python, Doug Hellmann's 'PyMOTW' (Python Module Of The Week) blog-series was one of the best resources to learn Python's standard library.

His series later culminated in the book: 'The Python Standard Library By Example'.

The PyMOTW entry on `unittest` was a great introduction to unit testing in Python. Since the PyMOTW version is getting quite outdated, I updated the `unittest` module entry.

This new version includes some edits and updates to the text, and all code and examples have been updated to reflect Python 3.3.

Have a look at my updated Python 3.3 version:
