Python Object Notification Framework for messaging

[chris]

Evaluate whether this would be a useful option for Eddie messaging.

"The NotificationFramework? is a python implementation of the "Observer" Design Pattern, allowing one-to-many dependency between objects, where an object (the subject) can tell to an unknown number of objects (the observers) that an event occurred (typically, that the object has changed), without having any idea of who the observers are and where they live (abstract, minimal coupling)."
