Context

In creating this project, I explored technical precedents, fleshed out a personality for the bot, and made a prioritization matrix comparing feature importance vs. effort to implement.  While there were plenty of Ruby-based Mastermind programs on GitHub, I did not find any that communicated with the user via SMS.  Some starting points are listed below:

1.) https://github.com/zottwickel/Mastermind This is a simple project where the computer picks a color and the user tries to guess it. Because the code has a length of one, the evaluation does not have a function for determining if an element is correct but in the wrong order.

2.) https://github.com/JonathanYiv/mastermind This is a more exhaustive and robust version of the first precedent and even uses the gem “colorize” to provide colored output in the command line.

3.) https://github.com/SadieD/oop_with_ruby/tree/master/mastermind this version works with numbers from 1-6 instead of colors.
