//       Class : Pipeline
// Description : This class manages a staged pipeline of data, for
//               instance the render pipeline, so that each stage of
//               the pipeline can simultaneously access different
//               copies of the same data.  It actually maintains a
//               collection of PipelineCycler objects, and manages the
//               turning of all of them at once.
//
//               There is one default Pipeline object, the render
//               pipeline.  Other specialty pipelines may be created
//               as needed.
