Detailed Description

       Bridge between QwtSeriesStore and QwtPlotSeriesItem.

       QwtAbstractSeriesStore is an abstract interface only to make it possible to isolate the template based
       methods ( QwtSeriesStore ) from the regular methods ( QwtPlotSeriesItem ) to make it possible to derive
       from QwtPlotSeriesItem without any hassle with templates.
