Subject: add coordinate option to r.reclass and r.recode

Platform: Mac OSX
grass binary for platform: Downloaded precompiled Binaries
GRASS Version: 6.1 cvs 2005/11/19

I'd like to suggest that r.reclass and r.recode be updated to permit specification
of cells to reclass/recode by coordinate as well as by cat number. Currently,
both support...

cat1 cat2 cat3 thru cat4 = 1

My suggestion is that they also support...

x1,y1 x2,y2 x3,y3 thru x4,y4 = 1

This opens up a number of new possiblities through the option of reclassification/recoding
by geography rather than attribute. For example, uses in scripting or other programming,
it could be used for modeling of dynamic phenomena--weather fronts, mobile agents,
animal herds, vegetation spread, etc.
