[aprssig] Why Not "Gate in Vicinity" (phones)

Yes, UI-View can do that, but what it can't do is something like "Gate 
APRS-IS-only stations that are nearby but only posits and at most this 
many per time interval".  Nearly all of the IGate software out there 
(except my own APRSISCE/32, a situation which will soon be remedied) 
provides some ability for specific stations to be gated, but that gates 
ALL packets from those stations (within rate limits if supported), not 
just posits and no provision for "close" but un-enumerated stations.
