Defines two simple but multithreaded renders, a level-set ray tracer and a volume render. To support these renders we also define perspective and orthographic cameras (both designed to mimic a Houdini camera), a Film class and some rather naive shaders.

- These classes are included mainly as reference implementations for ray-tracing of OpenVDB volumes. In other words they are not intended for production-quality rendering, but could be used for fast pre-visualization or as a starting point for a more serious render.
