Nornals are not affected by the noise. Sample nearby heights or perhaps directly calculate normals

Set up heroku so that staging and master branches are automatically deployed for demos

https://github.com/Rudraksha20/Procedural-3D-Tiles-Server has some working terrain with multi-value octave noise. This should be incorporated into the cpp-bindings branch

Terrain generation is simple multioctave noise. Investigate using a more realistic noise function and using more real-world inspired generation.

Some thoughts:

• on Earth, terrain is mostly indiscernible except at closer distances. It seems like the starting noise frequency is high relative to the size of the planet
• should we start with feature detemination? It may be difficult for simple noise generation to generation emergent features like oceans and plains

Noise looses continuity at the poles. Evaluate a better method of noise generation

Currently geometric error is the integral of the max amplitude of the remaining octaves plus the greatest distance between the chord and true arc spanning a particular tile. At close distances there seem to be far too many small tiles.

Instead of generating terrain in Javascript and running a glTF json through gltf-pipeline, we should instead manually create the .b3dm buffers in a C++ module. tileset.json generation should also happen in C++

Add tests and set up Travis CI builds
