//  Class: avtInlinePipelineSource
//
//  Purpose:
//      There are occasions where a pipeline is "inlined" inside another
//      pipeline.  When that occurs, the there needs to be a new terminating
//      source -- avtInlinePipelineSource.  That source should be smart enough
//      to act like its own terminating source in some instances and to bypass
//      to the pipeline's real terminating source in others.
//
//  Programmer: Hank Childs
//  Creation:   September 11, 2001
//
//  Modifications:
//    Jeremy Meredith, Wed Jun  9 09:14:57 PDT 2004
//    Added species aux data.
//
//    Hank Childs, Sat Mar  5 18:36:02 PST 2005
//    Turn off load balancing for inline pipeline sources.
