Workspace Method SurfaceBlackbody

Description

Blackbody surface, with support for Jacobian calculations.

See surfaceBlackbody and SurfaceFastem for complementary
information.

For this method, surface_props_data must contain these data:
  "Skin temperature"

dsurface_emission_dx is calculated analytically.
surface_rmatrix and dsurface_rmatrix_dx are set to 0.
