class AbstractObserver
The base class for all instantiations of
the Observer and NObserver template classes. 
class NObserver
This template class implements an adapter that sits between
a NotificationCenter and an object receiving notifications
from it.
class Notification
The base class for all notification classes used
with the NotificationCenter and the NotificationQueue
classes.
class NotificationCenter
A NotificationCenter is essentially a notification dispatcher.
class NotificationQueue
A NotificationQueue object provides a way to implement asynchronous
notifications.
class Observer
This template class implements an adapter that sits between
a NotificationCenter and an object receiving notifications
from it.
class PriorityNotificationQueue
A PriorityNotificationQueue object provides a way to implement asynchronous
notifications.
class TimedNotificationQueue
A TimedNotificationQueue object provides a way to implement timed, asynchronous
