// .NAME vtkThreadedCompositeDataPipeline - Executive that works in parallel
// .SECTION Description
// vtkThreadedCompositeDataPipeline processes a composite data object in
// parallel using the SMP framework. It does this by creating a vector of
// data objects (the pieces of the composite data) and processing them
// using vtkSMPTools::For. Note that this requires that the
// algorithm implement all pipeline passes in a re-entrant way. It should
// store/retrieve all state changes using input and output information
// objects, which are unique to each thread.
