Added an initial ability to create an unstructured grid on a planar region bounded by a string of points.
Fixed a bug that could cause transformed versions of geometry objects to loose track of the user data associated with the child objects.
Added a method that returns the GeomSSScene associated with the window. This is primarily to support writing debugging code that can draw to the 3D view while running.
Modified GeomPoint to conform to the new XYPoint interface (which will be used in future updates).
Added a "normal2D()" function that returns the in-plane normal vector to an input 2D vector.
Approved the robustness of the intersect(LineSegment line, Parameter too) method.
Added a series of methods that test the PointString:
Corrected a typo in the documentation.
