PiePoint is used to store an X point value (and optionally a label value).  This is used in the EJSC.PieSeries class store data for each pie piece to be drawn on the chart.  This object is created automatically by once data is made available via a EJSC.DataHandler descendant.  PiePoint objects should generally not be created manually.

The constructor expects the X value as well as the EJSC.PieSeries which owns the point and optionally (leave null if not used) label and userdata string values.
