streams-exercise.tests.py

This file is intentionally written without the benefit of the Python
unittest library. This can be used to demonstrate in-class that unit testing
is a simple concept which benefits from the use of a library, but does not
require it.

Run with `python tests.py`. The return code will be the number of test failures.
