#USAGE:
# resource (slate, grass, clay) picker
#stand on slate/grass and start macro and click on the button when mousepointer changes to +
#this program will keep scanning that exact location for an exact match of a 10x10 patch there
#if it sees one, it will click it
# will try others positions on the left too (icon wide)
