 * Description: This class represents a CyberPet that can
 *  eat and sleep on command. This version incorporates a
 *  String instance variable to represent the pet's name.

 *  Note that the instance variables are declared private.
 *  Public access methods, setName(), getName(), eat(), sleep(),
 *  provide an interface that limits the way other objects can
 *  change a CyberPet's state. This helps guarantee a consistent 
 *  internal state.
