   *       Functions: This file contains
   *           main
   *
   *       Purpose:
   *          This program creates an 8 bit tiff file
   *          of size l*ROWS by w*COLS.
   *
   *       External Calls:
   *          imageio.c
   *             create_allocate_tif_file
   *             create_allocate_bmp_file
   *
   *       Modifications:
   *          7 Arpil 1992 - created
   *         15 August 1998 - modified to work with
   *              an entire image array at once.
   *         18 September 1998 - modified to work with 
   *              all I O routines in imageio.c.
