14 * Wraps a Repository reducing traffic to the underlying repository for some
15 * requests. AugurRepository tags Resources leaving the Repository with the
16 * query that was used to retrieve it. When one of these resources is used as a
17 * binding to a new query it expands the new query to pro-actively retrieve the
18 * results for other resources with the same tag. This technique can change
19 * repository hits from O(n^m) into O(m) without changing how the data is
20 * accessed from the repository.
