-- function called by the on_step callback of the pipeworks tube luaentity.
-- the routine is passed the current node position, velocity, itemstack,
-- and owner name.
-- returns three values:
-- * a boolean "found destination" status;
-- * a new velocity vector that the tubed item should use, or nil if not found;
-- * a "multi-mode" data table (or nil if N/A) where a stack was split apart.
-- if this is not nil, the luaentity spawns new tubed items for each new fragment stack,
-- then deletes itself (i.e. the original item stack).
