pipeworks/item_transport.lua
Vanessa Ezekowitz 109729cfb2 Added Nore's item transport mod and integrated it into pipeworks
Items can now flow from one chest (or Nore's filter object) to another via the
pneumatic tubes!  Thanks to Nore and RealBadAngel for the code.

Note that this mod has to redefine the default chests and furnaces (see
compat.lua) in order to add some new group definitions so that tubes can
appear to connect to these objects.
