**The dimension of the intersection of two geometries, both of which are dimension .two, is either .zero,.one, .two., or .false**
if a line segment from one polygon boundary crosses over a line segment of the boundary of the other polygon, then return .two. If one polygon is completely contained inside another polygon, but not completely contained inside a hole within the first polygon, return .two. If the boundaries of the two polygons overlap perfectly, return .two. If the boundaries of the two polygons overlap on any sub-segment, return .one. If the boundaries of the two polygons touch at one or more points, return .zero, else return .false.
