Old description:
> For even more efficient generation of integer vectors... use Gray codes.
New description:
Gray codes are useful to iterate over complicated combinatorial structure.
We provide simple implementation of:
- a gray code for integer vectors (reflected mixed-radix)
- a gray code for combinations (revolving door)
