*
* Changes
* -------
* 22-Nov-2002 : Initial version completed
* Jan 2003 : Optimized advanceTime(), added implemnt'n of RangeInfo intfc
* (using cached values for min, max, and range); also added
* getOldestIndex() and getNewestIndex() ftns so client classes
* can use this class as the master "index authority".
* 22-Jan-2003 : Made this class stand on its own, rather than extending
* class FastTimeSeriesCollection
* 31-Jan-2003 : Changed TimePeriod --> RegularTimePeriod (DG);
* 13-Mar-2003 : Moved to com.jrefinery.data.time package (DG);
* 29-Apr-2003 : Added small change to appendData method, from Irv Thomae (DG);
* 19-Sep-2003 : Added new appendData method, from Irv Thomae (DG);
* 05-May-2004 : Now extends AbstractIntervalXYDataset. This also required a
* change to the return type of the getY() method - I'm slightly
* unsure of the implications of this, so it might require some
* further amendment (DG);
* 15-Jul-2004 : Switched getX() with getXValue() and getY() with
* getYValue() (DG);
* 11-Jan-2004 : Removed deprecated code in preparation for the 1.0.0
* release (DG);
* 02-Feb-2007 : Removed author tags all over JFreeChart sources (DG);
