 *
 *    Forward reference to SE_ConvertCoordSystemParams,
 *    defined in se_coord_conv.c. This allows the definition
 *    of SE_ConvertCoordSystem params to be hidden,
 *    while allowing the declaration of functions which
 *    can use it via SE_CONVERT_COORD_SYSTEM_PAIR.
 *
 *    This structure is used to optimize multiple
 *    coordinate conversion calls without permitting
 *    the user to see the API's internal data structure.
