Generic ARC caching implementation. This package makes a few assumptions
as modelled in the interfaces:
- It caches the contents of a BackingStore implementation which may be
disk-based, network-based or whatever.
- Each entity implements the Identifiable interface indicating that it
has the property of being uniquely-identifiable.
- Each entity is identified by an instance of the opaque type, Identifier.
