Class Notification

Notification objects are generally encountered when supplied by the NotificationCenter to its listener's callback method.

A Notification object is designed as an immutable object.

You should not need to directly instanciate Notification objects: rather, use NotificationCenter methods to add or remove observers and to post notifications.

Method Summary
	`__init__(self, name, object, userInfo)` This is the Notification initializer -- you should not directly instanciate a `Notification` object: rather, use `NotificationCenter` methods to add observers or to post notifications
	`__eq__(self, aNotification)` Two notifications are equal if and only if their names and objects are equal
	`__hash__(self)` Returns the hash code for the receiver
	`__ne__(self, aNotification)` Boolean negation of __eq__
	`__setattr__(self, name, value)` Raises `TypeError` since this is an immutable object
	`__str__(self)` Returns a user-presentable string representing the object
	`name(self)` Returns the receiver's field 'name'
	`object(self)` Returns the receiver's field 'object'
	`userInfo(self)` Returns the receiver's field 'info'

setattr(self, name, value)

Raises TypeError since this is an immutable object

str(self)
(Informal representation operator)

Returns a user-presentable string representing the object
