Setting up in the application code for Heroku

Now we can turn our attention towards the application code because before we can deploy to Heroku, we will need to make two changes to the code. These are things that Heroku expects your app to have in place in order to run properly because Heroku does a lot of things automatically, which means you have to have some basic stuff set up for Heroku to work. It's not too complex—some really simple changes, a couple one-liners.
