check the live env now. for example, it seems that certain statements
written to print out number of shared arcs dont work now. this is
because observations were dropped for lack of observations within the
polygons. but this should not behave like this. also, need to check out
whether shared.arcs.idx is giving the right index. it seems, when you
check against abt.poly.idx[,3] that ALL of the arcs in abt.poly.idx[,3]
are shared. is that right? if so why was shared.arcs.idx written?
