Detailed Description

Optimized implementation of the "intersects" spatial predicate for cases where one Geometry is a rectangle.

This class works for all input geometries, including GeometryCollections.

As a further optimization, this class can be used to test many geometries against a single rectangle in a slightly more efficient way.
