Definitions and implementations of shapes composed several line segments:
polylines, rings, polygons. Contains several polygon implementations, to
manage the different types of polygons.
Package organization:
- Polygons:
- Polylines:
- LinearCurve2D: abstract class for any type of polyline
- Polyline2D: implementation for open polyline
- LinearRing2D: implementation for closed polylines, typically polygon boundaries
- Utility class:
