-- Pipeworks mod by Vanessa Ezekowitz - 2012-08-05

-- Entirely my own code.  This mod supplies various shapes of pipes
-- and devices that they can connect to such as pumps, valves, etc.
-- All pipes autoconnect as you lay them out, and devices will auto-
-- connect to them.

-- Un-comment the following dofile line to re-enable the old pipe nodes.
