Design pattern: Bridge

Description: "Decouple an abstraction from its implementation so that the two can vary independently."

This pattern can be used with both classes and prototypes.

In this sample implementation, we use classes for representing the abstraction part of the pattern and prototypes for the implementation part. As discussed in the pattern description, the instances in the abstraction hierarchy use object composition to refer to and delegate operations to the implementation hierarchy objects.
