/***********************************************************
* Creational - Abstract Factory
* Creates an instance of several families of classes
************************************************************
*
* Definition: Provide an interface for creating families
* of related or dependent objects without
* specifying their concrete classes.
************************************************************
*
* Participants:
* The classes and objects participating in this pattern are:
*
* AbstractFactory (ContinentFactory)
* declares an interface for operations that create abstract products
*
* ConcreteFactory (AfricaFactory, AmericaFactory)
* implements the operations to create concrete product objects
*
* AbstractProduct (Herbivore, Carnivore)
* declares an interface for a type of product object
*
* Product (Wildebeest, Lion, Bison, Wolf)
* defines a product object to be created by the corresponding concrete factory
* implements the AbstractProduct interface
*
* Client (AnimalWorld)
* uses interfaces declared by AbstractFactory and AbstractProduct classes
