This PR adds an iterator selection function, choice(), that takes an ExactSizeIterator and chooses a random value from it. In addition, I reimplement functions like alphanumeric() using choice().
Right now, the API returns Option<I::Item>, since an iterator could be empty. However, it may be slightly more idiomatic to have it return I::Item and panic if given an empty/buggy iterator.
