IndexedPointInAreaLocator class

Determines the {@link Location} of {@link Coordinate}s relative to an areal geometry, using indexing for efficiency. This algorithm is suitable for use in cases where many points will be tested against a given area.

The Location is computed precisely, in that points located on the geometry boundary or segments will return {@link Location.BOUNDARY}.

{@link Polygonal} and {@link LinearRing} geometries are supported.

Thread-safe and immutable.
