-- 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.
