#polygonize ⇒ RGeo::Feature::GeometryCollection

Polygonizes a set of Geometries which contain linework that represents the edges of a planar graph.

All types of Geometry are accepted as input; the constituent linework is extracted as the edges to be polygonized.

The edges must be correctly noded; that is, they must only meet at their endpoints and not overlap anywhere.
