// Code for the Third Checkpoint
// Tutorial: https://jesselawson.org/rust/get-started-with-rust-by-building-a-tiny-markdown-compiler/
// 
// The purpose of this checkpoint is to ensure that you have a complete copy
// of the code in the tutorial up to the checkpoint. I want you to tinker and
// explore, but to keep up with the rest of the tutorial, make sure your
// code matches this checkpoint.
