/* LAB:
Use nested classes with Vehicle class.
Design a class for Brand of a car.
Brand is going to store:
make and model of a car.
You also had year, mileage and price as part of the Vehicle class.

After you modify and TEST the class by using individual
variables, you are going to instantiate an array of 3
Vehicle objects. Read in and display data for the objects
in the array.
