 * Purpose:     This program is to generate HDF5 data files used to test

 *
 * Description
 * ===========
 *              gen_bounds.c will generate the following files:
 *              - bounds_earliest_latest.h5
 *              - bounds_earliest_v18.h5
 *              - bounds_latest_latest.h5
 *              - bounds_v18_latest.h5
 *              - bounds_v18_v18.h5
 *              These files are copied to 1.6 and 1.8 libraries for verifying
 *              that they can or cannot read particular file format.
