In this lesson, we continue with our discussion of the Simple Factory by beginning to implement it in our plugin. We're going to move forward by adding a couple of new classes all based on the diagrams we reviewed in the previous lesson.

During this lesson, we begin by implementing our `Social_Network` class, its subclasses, and the Simple Factory class. This sets the stage for the next lesson in which we begin refactoring our code to implement the Simple Factory pattern.
