  Provides: autocrafting, resource limits, on-demand crafting, storage stocker.

  Using a turtle allows for crafting of items eliminating the need for AE/RS
  molecular assemblers / crafters.

  Inventory setup:
    Turtle/computer must be touching at least one type of inventory

    Generic inventory block such as:
      Vanilla chest
      RFTools modular storage
      Storage drawers controller
      and many others...

    Applied energistics
      AE cable or interface (depending upon AE/MC version)

    Refined storage
      TODO: add required block

  Turtle crafting:
    1. The turtle must have a crafting table equipped.
    2. Equip the turtle with an introspection module.

  Controller (optional):
    Provides the ability to request crafting from AE / RS

    Applied Energistics
      In versions 1.7x, AE can be used for both inventory access and crafting
      requests.

      In versions 1.8+, AE can only be used to request crafting.

    Refined Storage
      In versions 1.8x, inventory access works depending upon version.

      Turtle/computer must be touching an interface for inventory access. If only
      requesting crafting, the controller must be either be touching or connected
      via CC cables.

  Configuration:
    Configuration file is usr/config/milo

    monitor        : valid options include:
                     type/monitor   - will use the first monitor found
                     side/north     - specify a direction (top/bottom/east/etc)
                     name/monitor_1 - specify the exact name of the peripheral
