Loads a gravity model
[gravmod] = CL_fo_gravityLoad(fname, [, incel])
Loads a gravity model from a file.
The function creates and returns a structure containing the data that describe the gravity model (spherical harmonics). The file must conform to the syntax used for gravity models.
If the incel ("in CelestLab") argument is true, the files are looked for in the directory: CL_home()/data/potential.
(string) Name (or path) of gravity file (1x1)
(boolean, optional) %t if the file is looked for in CelestLab database. Default is %f.
(structure) Gravity model (spherical harmonics).
