module Surrounded

This module should be added to objects which will enter into context objects.

Its main purpose is to keep a reference to the context and to implement method_missing to handle the relationship to other objects in the context.

Extend your classes with Surrounded::Context to handle their initialization and application of behaviors to the role players passed into the constructor.

The purpose of this module is to help you create context objects which encapsulate the interaction and behavior of objects inside.
