XYPoint is used to store a X,Y point value.  This is used in series such as EJSC.LineSeries, EJSC.AreaSeries, EJSC.ScatterSeries and EJSC.BarSeries to store each point to be drawn on the chart.  This object is created automatically by each series once data is made available via a EJSC.DataHandler descendant.  XYPoint objects should generally not be created manually.

The constructor expects the X and Y values as well as the EJSC.Series which owns the point and an optional (leave null if not used) userdata string value.
