You should be very familiar with the Enumerable module that gets mixed into the Array and Hash classes (among others) and provides you with lots of handy iterator methods. To prove that there's no magic to it, you're going to rebuild those methods.

We will explain an example of how an enumerable works to give you an idea of how to start tackling these methods. Specifically we're going to break down the `#find` enumerable method. The `#find` method finds the first element that matches the given block's condition and returns it. If one isn't found, it returns `nil`.
