/** \class TemporalDataObject
* \brief DataObject subclass with knowledge of temporal region
*
* This class represents a data object that relies on temporal regions. It uses
* an itk::RingBuffer to store DataObject pointers in sequential order. The
* pointers in the ring buffer should correspond to the BufferedTemporalRegion.
* The LargestPossibleTemporalRegion should indicate the maximum extent that
* data object is logically capable of holding, and the RequestedTemporalRegion
* is used in the pipeline to request that a certain temporal region be
* buffered
