// .NAME vtkPVCacheKeeper - manages data cache for flip book animations.
// .SECTION Description
// vtkPVCacheKeeper manages data cache for flip book animations.
// When caching is disabled, this simply acts as a pass through filter.
// When caching is enabled, is the current time step has been previously cached
// then this filter shuts the update request, otherwise propagates the update
// and then cache the result for later use. The current time step is set using
// SetCacheTime().
