      Collection and CollectionCatalogEntry are basic objects stored in the catalog. They were created for different purposes: Collection provides an interface to do operations on a collection; CollectionCatalogEntry serves as a cache for the on-disk catalog entry. However, they do share some data such as pointer to underlying recordStore, ns, uuid and so on. This ticket is to find out if there is a way to merge them (or make composition) to eliminate some unnecessary data copy.
