This is a piechart implementation.

PieChart class extends Chart from SWTChart. It adds a PaintListener and a PieChartSeries methods.
PieChartPaintListener implements a PaintListener, gets the PieSeriesArray and calculates the angles to draws the primitives in the paintControl method.
IColorsConstants is an interface of swt.graphics.RGB  colors.
