/**
*
* The Abstract Factory pattern provides a way to encapsulate a group of individual
* factories that have a common theme without specifying their concrete classes. In
* normal usage, the client software creates a concrete implementation of the abstract
* factory and then uses the generic interface of the factory to create the concrete
* objects that are part of the theme. The client does not know (or care) which
* concrete objects it gets from each of these internal factories, since it uses only
* the generic interfaces of their products. This pattern separates the details of
* implementation of a set of objects from their general usage and relies on object
* composition, as object creation is implemented in methods exposed in the factory
* interface.
