_D_e_s_c_r_i_p_t_i_o_n:

     Compute g, the acceleration due to gravity, as a function of
     latitude.

_U_s_a_g_e:

       g <- gravity(lat, degrees=TRUE);

_A_r_g_u_m_e_n_t_s:

     lat: Latitude in degN or radians north of the equator.

 degrees: Flag indicating whether degrees are used for latitude; if set
          to 'FALSE', radians are used.

_D_e_t_a_i_l_s:

     Value not verified yet, except roughly.

_V_a_l_u_e:

     Acceleration due to gravity [m^2/s].
