@NAME       : nd_loop.h
@DESCRIPTION: Header file for nd_loop.c
@METHOD     : Use these routines in the following way:

   Set start, end and increment vectors to define looping;

   nd_begin_looping(start, current, ndims);
   while (!nd_end_of_loop(current, end, ndims)) {
      nd_update_current_count(current, increment, end,
                              current_count, ndims);

      Use current and current_count to work on hyperslab;

      nd_increment_loop(current, start, increment, end, ndims);
   }
