# Notes:
# This is a basic project that I adapted from codeacademy.  As it stands
# right now it has limited functionality (as you can see)
# My goals for the project are as follows:
#
# TODO:
# 1.) write a class / class methods
# 2.) enable the user to loop back to the initial prompt, and exit when they
#     want to.
# 3.) use mongodb for the database, or maybe postgres I suppose.  I'd like to
#     learn some more about mongo.  I know I asked you once if you have used
#     mongo before, I don't remember what you said.
# 4.) Eventually make this a Rails-based web application.
#
# A project like this would be a good opportunity to learn git-flow
# and implement feature branches.  Let me know what you think.
