Place functions within their own files.

It's a good idea to separate out functions into bins or buckets of similar other code. This will allow us to keep the project more organized as time goes on.

Responsibilities of this task are simple:
1. Create a directory and file structure to support the project moving forward.
2. Break the functions in `main.rs` out into the newly created directories and files.
3. Import the functions into the `main.rs` file so they can still be used

This task may seem daunting but it's not as difficult as it sounds, here's an example:
