Thanks to cmd2's built-in transcript testing capability, it also serves as a test suite for example.py when used with
the exampleSession.txt transcript.
Running `python example.py -t exampleSession.txt` will run all the commands in the transcript against example.py,
verifying that the output produced matches the transcript.
