Expand description

Find added/removed references in blocks. If a Cid is referenced multiple times it will also returnes multiple times. This diff works recursively - all added/removed Cid at any depth will be returned. However there is a look-ahead depth limit, how many nodes are looked down to reuse references (defaults to 1).
