Add .gitignore and .gitattributes.
Add license and sample image.
Add project files.
Add castRay8 function and time it as well to see the difference between 1 and 8 rays. On my machine I'm getting 18ms vs 9ms so the 8 ray version is about twice as fast. I tried writing a castRay16 but it crashed. Possibly because my machine doesn't have the AVX512 instructions supported on my CPU, although I thought there would be a fallback but maybe not. Only write out the image once still. Make the light direction a global constant.
Add screenshot of the generated image
