Subject: [GRASSLIST:4553] s.cellstats implementation

I've posted an implementation of "s.cellstats", a program to calculate
univariate statistics for sites on a per cell basis.  It is adapted
from s.univar and the result of some discussions with Gordon Keith.

If folks would like to give it a whirl:
http://pweb.jps.net/~egm2/grass/s.cellstats/s.cellstats.html

I will be adding it to the GRASS source tree before too long, unless
there is some objection...

-------------------------------------------------------

s.cellstats (and s.univar) does 12 statistics, including coefficent of 
variance.

Gordon
