Overview

A class that can be used to create a group of notifier objects with the intent of representing a leveled notification system for irb.

This class will allow you to generate other notifiers, and assign them the appropriate level for output.

The Notifier class provides a class-method Notifier.def_notifier to create a new composite notifier. Using the first composite notifier object you create, sibling notifiers can be initialized with #def_notifier.
