A base <code>INotification</code> implementation.
<P>
PureMVC does not rely upon underlying event models such
as the one provided with Flash, and ActionScript 3 does
not have an inherent event model.</P>
<P>
The Observer Pattern as implemented within PureMVC exists
to support event-driven communication between the
application and the actors of the MVC triad.</P>
<P>
Notifications are not meant to be a replacement for Events
in Flex/Flash/Apollo. Generally, <code>IMediator</code> implementors
place event listeners on their view components, which they
then handle in the usual way. This may lead to the broadcast of <code>Notification</code>s to
trigger <code>ICommand</code>s or to communicate with other <code>IMediators</code>. <code>IProxy</code> and <code>ICommand</code>
instances communicate with each other and <code>IMediator</code>s
by broadcasting <code>INotification</code>s.</P>
<P>
A key difference between Flash <code>Event</code>s and PureMVC
<code>Notification</code>s is that <code>Event</code>s follow the
'Chain of Responsibility' pattern, 'bubbling' up the display hierarchy
until some parent component handles the <code>Event</code>, while
PureMVC <code>Notification</code>s follow a 'Publish/Subscribe'
pattern. PureMVC classes need not be related to each other in a
parent/child relationship in order to communicate with one another
using <code>Notification</code>s.
