Detailed Description

Listeners attach to Tellers.

A Listener can hook() to a Teller. The Teller will tell it when it mutates using Listener::tell(), usually through the highter lever Teller::tellListeners(). The Listener can later unhook(). The Listener must therefore implement Listener::tell() to react when it is told.
