  // = TITLE
  //    Defines a class that encapsulates behaviour of the Cubit client
  //    example.  Provides a better understanding of the logic in an
  //    object oriented way.
  //
  // = DESCRIPTION
  //    This class declares an interface to run the example client for
  //    Cubit CORBA server.  All the complexity for initializing the
  //    server is hidden in the class.  Just the run() interface is needed.
