Detailed Description

Represents a manager for big resources. Also provides the class factory for the Flyweight_Class instances that are associated with a particular big resource.

Note: The raw resource is provided by the caller and an ID is then associated with it. The ID is returned to the caller who then passes that ID to the Flyweight_Class factory along with a context.

In the exercise, only one big resource is ever created so this class is likely overkill for an example but it fully shows the architectural context in which a flyweight class is utilized.
