// CLASS DECLARATION

/**

* Class for mobile terminated MCE sessions.

*

* CMceInSession represents incoming invitation to join in a session.

*

* The characteristics of the session are defined by remote terminal. Theses charactereistics

* are defined using SDP and are turned by MCE server into structure of media streams attached 

* into the session. The user of this class is then responsible to either reject accept

* the invitation.

*

* Accepting the invitation is executed in two steps. First after receiving the invitation

* the user must complete the media structure. Streams attached to the session are not complete,

* but they must be completed by the user. Those componens defined in SDP are put automatically

* into media structure (like streams and RTP sinks and sources), but other relations must

* be completed by user. When media structure is complete, UpdateL method is called and session

* establishement continues with second step.

*

* After all media resources are succesfully negotiated and reserved, session state is changed

* to Proceeding, and end used can be alarmed about incoming invitation. Typically, at this state

* 180 Ringing response is sent to network. If end user accepts the invitation, 200 OK is

* sent to network and session is established.

*

* After the session has been succesfylly established, it can be later updated and

* must be finally terminated.

*

* This class is never instantiated by user, but the ownership is in any case transferred

* to it. See class MMceInSessionObserver.

*

* If for any reason instance of this class is deleted while in established state,

* session is automatically terminated by MCE server.
