+/**
+* Base class for MCE events, inherited by both CMceInEvent and CMceOutEvent.
+*
+* CMceEvent represents peer-to-peer connection made with remote terminal.
+* This connection is also known as dialog and it is set up using SIP SUBSCRIBE
+* method.
+*
+* MCE events are typically used for queurying state of some parameter of 
+* remote terminal. The queuried parameter is known as event header.
+* The changes of this parameter are notified to another terminal by sending
+* SIP NOTIFY messages.
+*
+* The event can be finally terminated by either endpoints.
+*
+* If for any reason instance of this class is deleted while in active state,
+* event is automatically terminated by MCE server.
