/* RSC IDENTIFIER: GEOTRANS ENGINE                 
 *
 * ABSTRACT
 *
 *    This component is the coordinate transformation engine for the GEOTRANS
 *    application.  It provides an external input interface that supports the
 *    GEOTRANS GUIs (Motif and Windows) and the GEOTRANS file processing
 *    component.
 *
 *    This component depends on the DT&CC modules:  DATUM, ELLIPSOID,
 *    GEOCENTRIC, GEOREF, MERCATOR, TRANSVERSE MERCATOR, UTM, MGRS, POLAR
 *    STEREOGRAPHIC, UPS, LAMBERT_1, LAMBERT, ALBERS, AZIMUTHAL EQUIDISTANT, BONNE, 
 *    BRITISH NATIONAL GRID,  CASSINI, CYLINDRICAL EQUAL AREA,ECKERT4, ECKERT6, 
 *    EQUIDISTANT CYLINDRICAL, GNOMONIC, LOCAL CARTESIAN, MILLER, MOLLWEIDE, 
 *    NEYS, NEW ZEALAND MAP GRID, OBLIQUE MERCATOR, ORTHOGRAPHIC, POLYCONIC, 
 *    SINUSOIDAL, STEREOGRAPHIC, TRANSVERSE CYLINDRICAL EQUAL AREA, and VAN DER GRINTEN.
 *
 *
 * ERROR HANDLING
 *
 *    This component checks for error codes returned by the DT&CC modules.
 *    If an error code is returned, it 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 listed below.
 *
 *
 * REUSE NOTES
 *
 *    GEOTRANS ENGINE is intended for reuse by other applications that require 
 *    coordinate conversions between multiple coordinate systems and/or datum 
 *    transformations between multiple datums.
 *
