1.  class ConnectedInteriorTester extends AnyRef
2.  class ConsistentAreaTester extends AnyRef

   Checks that a {link GeometryGraph} representing an area (a {link Polygon} or {link MultiPolygon} ) has consistent semantics for area geometries.

   Checks that a {link GeometryGraph} representing an area (a {link Polygon} or {link MultiPolygon} ) has consistent semantics for area geometries. This check is required for any reasonable polygonal model (including the OGC-SFS model, as well as models which allow ring self-intersection at single points)

   Checks include:

   • test for rings which properly intersect (but not for ring self-intersection, or intersections at vertices)
   • test for consistent labelling at all node points (this detects vertex intersections with invalid topology, i.e. where the exterior side of an edge lies in the interior of the area)
   • test for duplicate rings

   If an inconsistency is found the location of the problem is recorded and is available to the caller.

3.  class IndexedNestedRingTester extends AnyRef

   Tests whether any of a set of {link LinearRing}s are nested inside another ring in the set, using a spatial index to speed up the comparisons.
