// .NAME vtkSQLogSource - A ParaView UI for the SciberQuest Log.
// .SECTION Description
// A dummy pipeline object (produces no data) providing a server
// manager UI for the SciberQuest Log. Applications may turn logging
// on and off view the GlobalLevel ivar. The data gathered by the log
// is written by the mpi root rank when this object is destroyed. Therefor
// this object must destroyed before MPI_Finalize is invoked.
