 *  This header file is part of the General Astrodynamics Library  
 *
 *  Description:
 *
 *     This header file includes the header files of the routines that make
 *     up the ellipsoids sub-library, and defines the constants for the
 *     Ellipsoid Model identifiers. 
 *  
 *  Status: 
 *  
 *     Sub-library header file  
 *  
 *  Includes:
 *
 *     gal_emdetails.h                Get full details of Ellipsoid Model
 *     gal_emname.h                   Get the name of Ellipsoid Model  
 *     gal_emparams.h                 Get the parameters of Ellipsiod Model
