1. Please write a Python 3 program and show all the outputs.

Add a python module named rot13.py to the session03 dir in your student dir. This module should provide at least one function called rot13 that takes any amount of text and returns that same text encrypted by ROT13.

This function should preserve whitespace, punctuation and capitalization.

Your module should include an if __name__ == '__main__': block with tests (asserts) that demonstrate that your rot13 function and any helper functions you add work properly.

There is a short-cut available that will help you accomplish this task. Some spelunking in the documentation for strings should help you to find it. If you do find it, using it is completely fair game.

As usual, add your new file to your local clone right away. Make commits early and often and include commit messages that are descriptive and concise.

When you are done, if you want me to review it, push your changes to github and issue a pull request.
