Documentation
 # Chapter 12 guided grep project
 If you have something better to do with this crate name, open a GitHub issue, I am pretty prompt.
 I feel like my code is pretty easy to understand but if it isn't, please reference chapter 12 of
 the book, I only changed some organization things and var names.
