//
// This is where the app starts, and sets things up
// We require the packages we need, body parser and express, and then set up body parser to accept
// JSON and URL encoded values. We then include the `routes.js` file, in which we define the API
// end-points we're going to be using, and we pass it the `app` variable. Lastly, we specify the
// port to listen to for requests. In this case, port 3000.
