/* RSC IDENTIFIER:  Ellipsoid Library Implementation
 *
 * ABSTRACT
 *
 *    The purpose of ELLIPSOID is to provide access to ellipsoid parameters
 *    for a collection of common ellipsoids.  A particular ellipsoid can be
 *    accessed by using its standard 2-letter code to find its index in the
 *    ellipsoid table.  The index can then be used to retrieve the ellipsoid
 *    name and parameters.
 *
 *    By sequentially retrieving all of the ellipsoid codes and/or names, a
 *    menu of the available ellipsoids can be constructed.  The index values
 *    resulting from selections from this menu can then be used to access the
 *    parameters of the selected ellipsoid.
 *
 *    This component depends on a data file named "ellips.dat", which contains
 *    the ellipsoid parameter values.  A copy of this file must be located in
 *    the directory specified by the environment variable "MSPCCS_DATA", if
 *    defined, or else in the current directory, whenever a program containing
 *    this component is executed.
 *
 *    Additional ellipsoids can be added to this file, either manually or using
 *    the Create_Ellipsoid function.  However, if a large number of ellipsoids
 *    are added, the ellipsoid table array size in this component will have to
 *    be increased.
 *
 * ERROR HANDLING
 *
 *    This component checks parameters for valid values.  If an invalid value
 *    is found, the error code is combined with the current error code using
 *    the bitwise or.  This combining allows multiple error codes to be
 *    returned. The possible error codes are:
 *
 *  ELLIPSE_NO_ERROR             : No errors occured in function
 *  ELLIPSE_FILE_OPEN_ERROR      : Ellipsoid file opening error
 *  ELLIPSE_INITIALIZE_ERROR     : Ellipsoid table can not initialize
 *  ELLIPSE_NOT_INITIALIZED_ERROR: Ellipsoid table not initialized properly
 *  ELLIPSE_INVALID_INDEX_ERROR  : Index is an invalid value
 *  ELLIPSE_INVALID_CODE_ERROR   : Code was not found in table
 *  ELLIPSE_A_ERROR              : Semi-major axis less than or equal to zero
 *  ELLIPSE_INV_F_ERROR          : Inverse flattening outside of valid range
 *                                  (250 to 350)
 *  ELLIPSE_NOT_USERDEF_ERROR    : Ellipsoid is not user defined - cannot be
 *                                  deleted
 *

 *    approximating ellipsoids.
