-- registry of flowable node behaviours in new flow logic
-- written 2017 by thetaepsilon

-- the actual registration functions which edit these tables can be found in flowable_node_registry_install.lua
-- this is because the ABM code needs to inspect these tables,
-- but the registration code needs to reference said ABM code.
-- so those functions were split out to resolve a circular dependency.

-- checks if a given node can flow in a given direction.
-- used to implement directional devices such as pumps,
-- which only visually connect in a certain direction.
-- node is the usual name + param structure.
-- direction is an x/y/z vector of the flow direction;
-- this function answers the question "can this node flow in this direction?"
