This code is for part one the AI Class optional Natural Language Processing
programming assignment. See youtu.be/KuSg1wcty3s for the complete problem
definition.
We are given a string which has been encoded with a Caesar cipher:
http://en.wikipedia.org/wiki/Caesar_cipher, and our job is to decode it.
