# Solution for Challenge: Ruby Drill: The self Keyword. Started 2013-07-22T18:43:38+00:00
# There are two representations of self that one can use at any time:
# 1. When defining a class method, self refers to the current class
# 2. When using an instance of a class, self refers to the current instance
# Self refers to the object you are currently calling a method on
