Function wu_changes

pub fn wu_changes<T: PartialEq + Clone + Debug>(
    d: &[DiffResult],
    b: &[T],
) -> Vec<Change<T>>

Convert a slice of wu_diff::DiffResult into a Vec<Change>.

Note that unlike lcs_changes(), b is needed to clone inserted items because they are not included in the wu_diff::DiffResult.
