C# and F# versions of Kevin Beason's 99 line ray tracer.
The C# version is a modified version of Randy Ridge's C# version.
Reassuringly the C# and F# versions run in at very similar speed. F# is only slightly slower.
This was written as an exercise to learn about F# syntax. I was hoping it would be more consise to be honest but maybe there is more syntax for me to learn to make that happen.
