[Cu-wireless] NetStumbler map

Hi,

Oops, it's already 1:30am? :)

I did some programming to obtain a "map" of a NetStumbler output. Here is
the result (pitcure at the top):

The issue with that picture is that the NetStumbler dataset I collected
last Sunday has very bad GPS data in it, with huge jumps all over the
place (weather wasn't that good, we were under the roof, and the GPS only
had three or four satellites to use). So the image isn't really that
significant; but it shows the script I wrote somehow works and generates
an image. :)

Red-orange is "noise", green is "signal" (if somebody is color-blind in
the group and the colors I picked just don't do it for you, please let me
know). There's probably some fine-tuning to be done on the maths used to
compute the colors, but I'm going to bed now. :)
