100% Iron Farm with 32 Village Iron Titan. Working in 1.10 Pre-Release 1

Hi, This is my 100% efficient Iron Farm, and when I say efficient I mean that a golem can spawn into every location within the villages 16x16x6 golem spawning area. Very heavy on the resources but a fun and very different design, suitable for 1.8 and 1.9 and 1.10 (current pre-release 1), I added an Iron Titan to show spawn rates better.
