 This code uses a factory to create the Automobile object. There are two possible benefits to building your code this
 way; the first is that if you need to change, rename, or replace the Automobile class later on you can do so and you

 Using the factory pattern isn't always necessary (or wise). The example code used here is so simple that a factory
 would simply be adding unneeded complexity. However if you are making a fairly large or complex project you may save
