// Description:
// This test aims to test embedding feature of the application. The dll 
// launches tpackage application, all messages go via client-server
// architecture. Server leaves on the Testpackage step side and is started
// in the doTestStepL() function, client places on the tpackage application
// side. Server's thread creates and run active scheduler in order to maintain
// the active objects.\n
// It is relevant that logger uses the same thread in which it was created, 
// therefore when server receives  EMessageServSetFromString message from the 
// client it activates active object (CMessageActive) in order to output 
// log buffer into the file in the same thread as lives logger.  
// The CMessageActive class is activated by calling function 
// CMessageActive::RequestForTheMessageOutput(TInt aCode), 
// iStatus sets to aCode value.\n
// When client completes its work, it sends message  EMessageServStop and 
// server stops active sheduler so server's thread might be closed.\n
//

   @SYMTestPriority High
  
   @SYMTestStatus Implemented
   
   @SYMTestActions The dll creates a thread and starts a Message server. Once the
   message server is up and ready it launches the test client application,
   tpackage. The server installs and starts an active scheduler to service
   request messages received from the client and to log the information gathered
   from the request messages.When the server receives  EMessageServSetFromString
   message from the client, it activates CMessageActive active object in order
   to output the log buffer. When client completes its work, it sends message
   EMessageServStop and server stops active sheduler so that server's thread
   might be closed. 
  
   @SYMTestExpectedResults All messages send by the client should be processed by
   the server and outputted in the log file.
