added conversion constructors for foundation::Ray<> and foundation::RayInfo<>.
restricted SSE2-optimized specialization of foundation::bvh::Intersector to the 3D, double-precision case.
small code tweaks.
make sure to pick the SSE2-optimized specialization of foundation::bvh::Intersector to intersect triangle trees.
