 #
 # The goal of this exercise is work on identifying abstraction which helps simplify, document,
 # and separate the concerns going on in file.
 # 
 # Exercise:
 #   * Find related ideas in the below code
 #   * Abstract them out (methods, modules, classes, etc, you pick!)
 #   * If you find multiple ways, then do a separate gist for each way. 
 #   * Rinse repeat until you see no other ways.
 #
 # Note: there is not enough of the code-base to run this code, so in order to run
 #   the code you'll have to implement the missing pieces.
