// TSDistData - class for storing one data point and date.
//------------------------------------------------------------------------------
// Copyright:	See the COPYRIGHT file.
//------------------------------------------------------------------------------
// Notes:	(1)	This class holds one data point for a time series.  It
//			is used for data storage by the IrregularTS class and is
//			used by other TS classes to return a data point.
//------------------------------------------------------------------------------
// History:
// 
// 05 Mar 1998	Daniel Weiler,	Created initial version of class.
//		Riverside Technology, inc.
// 05 May 1998	Matthew J. Rutherford, RTi	Added two access routines
//						to help with the copy 
//						constructors.

// Variables:	I/O	Description		
//
// _data	C	Data value.
// _data_flag	C	Data flag (often used for quality, etc.).
// _date	C	Date associated with data value.
// _next	C	Pointer to next TSDistData in list (an internally maintained
//			linked list).
// _previous	C	Pointer to previous TSDistData in list (an internally
