Update to version 3.0

Hi,
version 3.0 is coming - see screenshot (1)! Smoothed (bezier spline patches) 3D surfaces based on irregular (kernel density or ordinary kriging) as well gridded data, interval surfaces, additional coords system - wired walls, colormaps and refactoring. Templates are now compatible with new 3.7 RC6 of POVRay. My plan is to publish everything until Christmas this year.
