s.voronoi update on moon

Voronoi diagrams and Delaunay triangulation are possible with 
the following GRASS programs 

   s.voronoi
   s.delaunay

Source code is in

   moon.cecer.army.mil:/grass/incoming/s.voronoi.cpio.Z

The cpio file was made with the following command:

  find src/sites/s.voronoi -print | /usr/bin/cpio -oc > ! s.voronoi.cpio

and thus should be extracted from the top level of your GRASS source
code heirarchy (try something like '/usr/bin/cpio -itc < s.voronoi.cpio'
to get a table of contents and '/usr/bin/cpio -icdu < s.voronoi.cpio' to 
extract).

Installation requires compilation of another program
(s.sweep) which goes in the ETC directory.  The Gmakefile takes
care of all of this, so the command 'gmake4.0' should
do everything except take care of the man pages. You should
copy these manually to the proper place.

This is a complete re-write of an earlier program: s.voronoi.
Many, many thanks to Harry Sharp <sharp at snuff.csd.scarolina.edu>
for doing most of the initial testing of this program and for
providing feedback.

ATTN GRASS4.1 folks: this is an update for an earlier submitted
program of the same name.

For those of you interested in spatial autocorrelation, s.voronoi
output is used by v.autocorr to calculate and do hypothesis testing
on Geary ratios and Moran coefficients. BTW, if anyone has the
LaTeX source to my tutorial on this subject, would you please mail 
it to me? (It seems to be misplaced at the moment - all that I have is the
PostScript version.) Thanks.
