OOP 1: Box

/*
 * This is a simple example class for learning and teaching Object-Oriented Programming.
 * It demonstrates encapsulation by using get and set methods for its properties.
 * It also demonstrates the fact that to the driver program, there is no difference between
 * a raw property like Length and a calculated property like Volume.
 *
 * For more Object-Oriented Programming fundamentals, see the Container class:
