Understanding Chain of Responsibility
The Chain of Responsibility pattern lets you pass requests along a chain of handlers. Each handler decides either to process the request or pass it to the next handler in the chain.

handles < 10
Handler2
handles < 20
Handler3
handles all
Request enters chain

Request Arrives
A request enters the chain.
