Implemented custom MultipleAreaSeries for support of drawing multiple areas in one series (for example for a soil layer which gets intersected by a surface line). Implemented the necessary classes to convert a soil layer geometry intersected by a surfaceline and draw the resulting geometry on the charting component. Temporarily added NetTopologySuite to Ringtoets.Piping.Forms for quick testing of the soil layer drawing functionality. Always notify the root collection of the ChartLegendView on changes of children.
