      *       Functions: This file contains no functions. It
      *          contains declarations of the data structures used
      *          by the C Image Processing Systems CIPS.
      *
      *   Purpose:
      *      To declare data structures.
      *
      *   Modifications:
      *      June 1990 = created
      *
      *      February 2016 - in this postmodern world, 
      *      on a Mac with OS X 10.10...
      *      Longs are 8 bytes
      *      INTS are 4 bytes
      *      FLOATS are 4 bytes
      *
      *      You have to declare some functions before you use them.
      *      See end of this file.
