PolyNodes are encapsulated within a PolyTree container, and together provide a data structure representing the parent-child relationships of polygon contours returned by Clipper's Execute method.
PolyNode objects represent single polygon contours that can be either 'outer' or a 'hole' polygons. PolyNodes may own any number of PolyNode children (Childs), where children of outer polygons are holes, and children of holes are (nested) outer polygons.
