FIND_LEADER(chunk c):
---------------------
order voronoi_neighbors(lvl 1) by dist to c.
leader is first in this list.


JOIN_CHUNK
-----------
leader <- find_leader()
if leader == self:
   old <- find_second_closest()
   get_copy(old)
else:
   get_copy(leader)


MODIFY_CHUNK
------------
leader <- find_leader()
if leader == self:
   send_broadcast_mod_with_ack(aoi)
else:
   ack <- send_broadcast_mod(aoi)
   if ack:
      just draw it


MOVE
----
new <- find_second_closest()
send_copy(new)


REPLICATE
---------
leader <- find_leader()
if leader == self:
   PROPAGATE(voronoi_neighbor(lvl 1), copy, MAX_LVL - 1)

PROPAGATE
---------
propagate until lvl == 0 to neighbors not in recv list


DELETE_REPLICATE
----------------
leader <- find_leader(copy)
hops <- dist_to(leader)
delete if hops > MAX_LVL


CONSISTENCY
-----------
mod <- get_mod_msg(aoi)
chk <- get_chunk_id(mod)
led <- find_leader(chk)
if chk == led:
   check_consistency
   send_broadcast_ack(yes|no)
