Checks consistency of geometric considerations of the atmosphere.

The following WSVs are checked: z_field, refellipsoid, z_surface, lat_true and lon_true. If any of the variables above is changed, then this method shall be called again (no automatic check that this is fulfilled!).

The tests include that:

1. refellipsoid has correct size, and that eccentricity is set to zero if 1D atmosphere.

2. z_field and z_surface have sizes consistent with the atmospheric grids.

3. There is no gap between z_surface and z_field.

4. A rough search of maximum gradient of the altitude of the pressure level closest to 500 hPa is made. If this value exceeds the GIN max500hpa_gradient an error is issued. Please note that the unit of this GIN is m per 100km. For normal conditions on Earth, large scale gradients of the 500 hPa level is in the order of 20m/100km.

lat_true and lon_true are allowed to be empty.

If any test fails, there is an error. Otherwise, atmgeom_checked is set to 1.
