 * Interface for client side storage. See

 * A storage object stores an arbitrary set of key-value pairs, which
 * may be retrieved, modified and removed as needed. A key may only
 * exist once within a storage object, and only one value may be
 * associated with a particular key. Keys are stored in a particular
 * order with the condition that this order not change by merely changing
 * the value associated with a key, but the order may change when a
 * key is added or removed.
