// The code commented out below is this app without modularization.  I am leaving this here for my notes.  I moved the app.get, post, put, and delete requests to burgers_controller, then required var router = express.Router(), then called router.get, post, put, and delete in that file.  At the end of that file, I exported the routes via module.exports = router, and imported them here with var routes = require('./controllers/burgers_controller.js'); and app.use('/', routes);

// See the note above to review the code below.
