iySurfaceLambertianDirect

This method calculates the scattering of the direct radiation for a Lambertian surface.

This method is designed to be part of iy_surface_agenda

Important this method calculates only the scattering of the direct (sun) radiation. No diffuse incoming radiation is considered

This method has no jacobian capability
