Deliverables

We've provided you with a console that you can use to test your code. To enter a console session, run ruby tools/console.rb from the command line. You'll be able to test out the methods that you write here. Take a look at that file to see how you can pre-define variables and create object instances, rather than manually doing it in every single console session.
