/**
 * A Ball is the name for a "generic" ball, that is, any Drawable, Selectable,
 * Morphable, Animate object that is also a BallDescriber.
 * 
 * <p>
 * Specific kinds of Balls are expected to do other things like move on their
 * own, bounce, shrink and grow in size, explode, and be draggable by the mouse.
 * 
 * <p>
 * <strong> Every class that implements Ball must have a constructor that takes
 * a World object. </strong>
