Abstract template for a notifier (or subject) in the Observer design pattern.
In the observer design pattern, a Notifier manages a list of registered Observer objects, and provides a method to notify all observers when some event occurs. A list of observer objects is maintained as a list of Observer pointers. The method Notifier::notifyObservers(Event&) method calls the the update(Event&) method of every Observer in the list.
The typename parameter Event is the type of the object that must be passed to the update() method of each observer. This type can name either a primitive C data type or a class, but must encode whatever information is required for any Observer to respond appropriately when notified.
