Hamster::Vector#permutation

Yields all permutations of length `n` of items from the `Vector`, and then
returns `self`. If no length `n` is specified, permutations of all elements
will be yielded.

There is no guarantee about which order the permutations will be yielded in.

If no block is given, an `Enumerator` is returned instead.
