Hella-Parallel Compute with RenderScript

Example app for RGB Rendering for Bitmaps and the camera viewfinder.
Associated talk: Hella-Parallel Compute with RenderScript at droidcon sf 2017.

Current state: The app works! It's mostly kotlin now. The Cool algebra part is WIP (see below).

Cool algebra, Lydia! Thanks!

This repo is also being used as a base-app and test harness for a new project. It's focused on trying to define an abstract algebra of Colors, Photos, and ColorCubes (3D LUTs), and implement it on Android using Renderscript. It's WIP, but pretty fun.
Note: As part of this I converted :hella and most of :app to Kotlin.
