+* **RefinedAbstraction**: Extends the interface defined by *Abstraction*
 * **`Implementor`**: defines the interface for implementation classes. This interface doesn't have to correspond exactly to Abstraction's interface; in fact the two interfaces can be quite different. Typically the Implementor interface provides only primitive operations, and Abstraction defines higher-level operations based on these primitives
