* @class vtkThreadedCompositeDataPipeline
* @brief Executive that works in parallel
*
* 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.
