+-- Autoconnect Hooks
+-- Nodes like conductors may change their appearance and their connection rules
+-- right after being placed or after being dug, e.g. the default wires use this
+-- to automatically connect to linking nodes after placement.
+-- After placement, the update function will be executed immediately so that the
+-- possibly changed rules can be taken into account when recalculating the circuit.
+-- After digging, the update function will be queued and executed after
+-- recalculating the circuit. The update function must take care of updating the
+-- node at the given position itself, but also all of the other nodes the given
+-- position may have (had) a linking connection to.
