/**
*  RImpsImClient2 API
*
*  Applications use IM service via RImpsImClient2 class. First, they need to
*  connect to the server by calling RegisterL() member function.
*  Immediately after that an error handler must be registered by 
*  RegisterErrorObserverL. 
*  
*  When everything is done, call Unregister() to end
*  the session.
*
*  A user of this API must be aware that raising/releasing
*  the PDP context may affect the response times of called functions.
*
*
*  Observer methods:
*  -----------------------
*  Client can be notified when a certain type of message is received 
*  from the remote server.
*  Client has to be connected in the server in order to get notify events.
*  If the client is disconnected by server by calling Unregister(), all notify
*  requests and possible incoming events are canceled. 
*
*  Notify events are session-specific, ie. if you have several RImpsImClients
*  connected to the server, each has its own notify requests. 
*
*  In order to use notify services, you need to implement MImpsImHandler2 
*  and give a pointer to your class in RegisterL.
*  Observer method doesn't need to do anything else than your application 
*  needs it to do.
*
*
*  Addressing:
*  -----------
*  WV CSP specification defines characters that must be escaped if they
*  occur within the User-ID, Resource or Domain portions of a Wireless Village
*  address. WV engine does NOT escape those characters on behalf of user 
*  application. WV CSP also denies usage of certain characters in UserID
*  totally.
