Simple RayTracer in C#

[JeWaVe]

I migrated Raytracer sample to C#, in an effort to show the code similarity. Final goal is to use that sample as a tutorial on how to migrate complex code base from single-thread C# to GPU using Hybridizer

I understand this is quite odd to push C# in the typescript samples repository, but licensing doesn't allow me to redistribute / modify samples code without creating a pull request here.

I kept the code in a dedicated directory.

This is the procedure which has been recommended to me by typescript team

When i said add the sample to this repo, i did not meant he C# one. I meant the TS one. This is a TypeScript sample repo.
