Names for worlds that are not in this VM, so a client joins them as it joins any
Cauldron2D.World: {:via, Cauldron2D.Net.Remote.Worlds, name}.
{:via, Cauldron2D.Net.Remote.Worlds, {:node, :"my_game@arcade", :pit}}
{:via, Cauldron2D.Net.Remote.Worlds, {:url, "http://arcade:2280", token, "pit"}}A node's world is started on that node when the name is first looked up and is its
pid from then on; a server's world by URL is a Cauldron2D.Net.Link.World in this
VM, one per server and arena, started on the first lookup. A URL name may carry a
fifth element, options for the link world.
