[Regular expressions](https://en.wikipedia.org/wiki/Regular_expression) (Regexes, for short) are patterns used to
match character combinations in strings. [`grep`](https://en.wikipedia.org/wiki/Grep) is a CLI tool for searching

In this challenge you'll build your own implementation of `grep`. Along the way we'll learn about Regex syntax and
how Regexes are evaluated.
