+/// Early out check PolyList
+///
+/// This class is used primarily for triggers and similar checks. It checks to see
+/// if any of the geometry you feed it is inside its area, and if it is, it stops
+/// checking for any more data and returns a true value. This is good if you want
+/// to know if anything is in your "trigger" area, for instance.
