        * 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
