Workspace Method iySurfaceFlatRefractiveIndexDirect

Description

This method calculates the specular reflection at a flat 
surface of the direct radiation.

This method is designed to be part of iy_surface_agenda

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

This method has no jacobian capability
