LoadLunarTopography:

--------------------------------------------------------------------------
   Reads in the Clementine data.
   It will automatically read the file gltm2b.topo.
   If no output arguments are found it will create a file Topography.txt
   with the s and c coefficients.
--------------------------------------------------------------------------
   Form:
   [s,c] = LoadLunarTopography( nH )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   nH            (1,1)  Highest harmonic 

   -------
   Outputs
   -------
   s             (:,:)  Normalized sine coefficients
   c             (:,:)  Normalized cosine coefficients
