      Description:This writes an array of integers as grey-level image
      using the PGM (PortableGrayMap) format.
      On Unix systems, man 5 pgm should give you a description of
      the PGM image format.

      Parameters:fname		 - name of file to be written
      [grayvals] - one-dim. array containing the pixel gray values,
      starting at the upper left corner and continuing

      height		 - height of image (no. of rows)

      Remarks:So far, only the plain ASCII variant of the PGM Format is

      Examples:(FancyImage.pgm) [grayvals] 255 24 16 writePGM
      This writes an image named FancyImage.pgm with the gray values
      from the array, having 16 columns and 24 rows.
