Implementation of the number theoretic transform (NTT) in Rust.

The NTT is a DFT over the ring Z/mZ. We use a fast divide-and conquer algorithm. The array size `n` must be a power of two. 

We allow composite moduli as long as `n` divides `phi(p^e)` for each prime factor p of the modulus, where `phi` is the Euler totient.
