This is used with a construct consisting of a vertical stack of

* some chest (I used wood/copper, it does not have to be big)
* a turtle (with this code)
* ender chest, bound to a pouch

Followed by these items to the NORTH!

logistics remote order pipe  (next to chest)
logistics provider pipe (next to turtle)
me interface (next to Ender Chest)

Bind your remote orderer to the remote order pipe,

The turtle monitors the ranges of import and export slots specified,
importing items it finds in the Import range into the ME and pushing
items from the chest into the export slots if one is open.
