<p>
Time series interface. Time series class is used for efficient
handling of time series data. Ussually time series contains a very large number
if relatively small elements which are ussually acessed in sucessive order.
To avoid overhead of loading from the disk each particular time series element,
this class group several subsequent time series elements together and store them
as single object (block).
</p><p>
As far as C# currently has no templates and
Perst need to know format of block class, it is responsibity of prgorammer
to create block implementation derived from TimeSeriesBlock class
and containing array of time series elements. Size of this array specifies
the size of the block.
