Final project: a ray tracer

The course concludes with a ray tracer (exercises/05_capstone/P4_raytracer.cpp). It renders 3D scenes of spheres and triangles into a PNG image, with Phong lighting, shadows and mirror reflections — pulling together classes, overloaded operators, inheritance with virtual methods, std::optional, std::unique_ptr and std::vector. See exercises/05_capstone/README.md for details.
