Design pattern: Chain of Responsibility
Description: "Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it."
This pattern can be used with both classes and prototypes.
In this sample implementation, we use prototypes and fixed successors in the chain of responsibility. But the successors could also easily be defined dynamically.
