One-sided reflection

Reflection2[S, B, C, D, N, <boolean>]
Here, if we choose "one-sided", only the facing side (given by vector N) is reflective.
For now, I treat non-reflective as full absorption: if a ray intersects the back side, its path terminates. I believe a closed (terminating) path will have heuristic value when generalizing the problem later to vector hardware.
But one step at a time!
