Workspace Method jacobianAddSurfaceQuantity

Description

Includes a surface quantity in the Jacobian.

The quantity is specified by the GIN-variable ``quantity``. The name
of the quantity must match the name used in surface_props_names.

For 1D or 2D calculations the latitude and/or longitude grid of
the retrieval field should set to have zero length.

The number of elements added to the state vector (x) is::

  n_g1 * n_g2

where n_g1 and n_g2 are the length of GIN ``g1`` and ``g2``, respectively.
Here empty vectors should be considered to have a length 1.
The elements are sorted with latitude as innermost loop and longitude
as outermost loop.
