PRE - Project Azide Gen 2 Plenoptic Rendering Engine

This Plenoptic Rendering Engine (PRE) began with the lefdy Objective Rendering Engine (ORE) as its baseline. The original lefdy/README has been renamed to README_lefdy.txt.

The Gen 2 hardware differs from Gen 1 by using the Raspberry Pi Zero as its compute module, rather than the Inforce 6410. By moving to the RasPi0, this engine must be ported from OpenGL to OpenGL ES.
