a version of graphcalc .paf

this is a gem of a small calculator that can graph like your overpriced t 89.

its gnu gpl so i think it would be a easy program to add... i don't even think it installs.

if you've never stumbled across it just download and play with it. its so easy and would be a wonderful addition to the apps.

edit: i was mistaken it does an install but i hope its not complex.
