This introduces a `textwrap::wrap_algorithms` module where the `wrap_first_fit` and `wrap_optimal_fit` functions now live. A new `WrapAlgorithm` trait replaces the old enum. This allows for arbitrary wrapping algorithms to be plugged into the library. We should also be able to change the return type from `Vec<&[Word]>` to `Iterator<Item = Word>` and thus implement streaming wrapping for the first-fit in the future. Fixes #325.
