One great benefit to classes is the ability to take a generic class
and then subclass it. Or the ability to instantiate various objects
from one class.

Say you have a dog class. If you pass in the correct data, you can
instantiate a dalmatian, a Labrador or a mutt. They're all dogs, but
their all different too.
