// DistributedTS - base class from which all sparse time series are derived

// Notes:	(1)	This base class is provided so that specific sparse
//			time series can derive from this class.
//		(2)	Data for this time series interval is stored either as
//			a linked list of TSData objects, or as an array 
//			depending on how the data are read in.
