//	Last Events

//

//	The most recent event to occur must be stored in the notification handler to be compared

//  with the event passed with CheckNotification(), so that they can be compared (if they are 

//  equal, the notification should not be completed).

//	Each TelObject to use this Notification handler has a last event associated with it.

//	The first time a TelObject calls RegisterNotification() to add a notification to the array, 

//	an entry is made in the iLastEvents array connecting this TelObject with an event (to start

//  with this is ENoEvent).

//	When the notification completes, the LastEvent entry remains, as even if a TelObject has no

//	notifications outstanding there must still be a record of its last event. This LastEvent

//	entry must only be removed when the TelObject is destroyed, hence in the destructor of 

//	each of CPhoneHayes, CLineHayes, CCallHayes and CFaxHayes RemoveClientFromLastEvents() is

//  called.
