// Class : PipelineCyclerLinks
// Description : This just stores the pointers to implement a
// doubly-linked list of PipelineCyclers for a
// particular Pipeline object. We use a hand-rolled
// linked list rather than any STL container, because we
// want PipelineCyclers to be able to add and remove
// themselves from this list very quickly.
//
// These pointers are inherited from this separate class
// so the Pipeline object itself can be the root of the
// linked list.
