Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args) ⇒ Object (private)

Overrides method missing to catch undefined methods. If method_name is one of the keys on attributes, returns the value of that attribute. If method_name is not one of attributes, passes up the chain to super.

method_name - Symbol of the name of the method we’re testing for. args - Array of arguments send with the original mesage. block - Proc of code passed with original message.
