This serves the same purpose as the `fix_rotation_nsew`, but is used to restrict the node's rotation after it's been hit with the screwdriver.
**`unifieddyes.select_node(pointed_thing)`**
Just what it says on the tin. :-) This function returns a position and node definition of whatever is being pointed at.
**`unifieddyes.is_buildable_to(placer_name, ...)`**
Again, another obvious one, returns whether or not the pointed node is `buildable_to` (can be overwritten by another node).
