***************************************************************************
********************** ARCVIEW EXTENSION ****************************
NEW ARCVIEW EXTENSION: GRASPIT.avx
Works only from version GRASP-S 3.2 and GRASP-R 2.5 and older. New tool to read lookup tables which is compatible with changes in predictor layers (e.g. climate change), plus useful tools related to GRASP
(Installation: this extension should be dropped in: ...:\ESRI\AV_GIS30\ARCVIEW\EXT32)
