This simple test is to test the builtin topics on the client side.
The test application creates participant, publisher, datawriter,
subscriber and datareader and looks for the builtin topic data via
the builtin subsciber in participant.

It also tests the ignore* interface in DomainParticipant.


Builtin topic basic function test:

  run_test.pl  

  - start the DCPSInfo server.
    
    ../../../../DDS/DCPSInfoRepo -o repo.ior -d domain_ids
    
  - start the unittest client with the orb initialized by the Service_Participant.
  
    ./bit -DCPSInfoRepo file://$iorfile
      
 
Ingore* interface tests are done by passing the -i option.
