//	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.
