PPCA raytracer

This is a ray tracing project for Principle and Practice of Computer Algorithms (CS1952) course. We followed the tutorial series Ray Tracing in One Weekend, and writed the code in Rust. To acquire extra points, I implemented several optimizations:

• Reduce Contention: only clone Arc when creating a thread; change Arc into reference in other places.
• Static Dispatch: use generics to reduce extra expenses.
• Code Generation: use procedural macros in Rust to generate the scene code statically.
• Advanced Features: add support for Tranform
