Path: Orbit/GravityModels

% Create a gravity map from a gravity model.
 Plots the acceleration due to gravity relative to the spherical gravity 
 (point mass model).

 Type GravityMap for a demo.
   gMap = GravityMap( lat, lon, alt, nN, nM, gravityModel, f )

   lat          (1,:)    Latitude (rad)
   lon          (1,:)    Longitude (rad)
   alt          (1,1)    Altitude (km)
   nN           (1,1)    Highest zonal harmonic (m = 0) (empty gives the max #) 
   nM           (1,1)    Highest sectorial and tesseral harmonic 
                         (empty gives the max #) 
   gravityModel  (.)     Data structure
                         .name (1,:) Model name
                         .mu   (1,1) Gravitational constant (km^3/sec^2)
                         .a    (1,1) Model earth radius (km)
                         .c    (n,n) Cosine coefficients
                         .s    (n,n) Sine coefficients
                         .j    (1,n) Zonal harmonics
                         .isNormalized (1,1)  Boolean
   f           (1,1)    Flattening factor

   gMap        (lat,lon)  Gravity map in (m/s^2)
