Summary
This PR adds a
CurvedPolygonclass and implements an algorithm for computing the intersections of curved polygons and their areas and centroids. It leaves out some special cases, including tangent polygon intersection and intersections of polygons whose component curves overlap for the following reasons:It also leaves out a full mesh-mesh intersection example, because I'd like to add arbitrary polynomial field transfer (not just areas and centroids) functionality before pushing a full example.
