MapStorageAccess class

A map-based storage plugin. You can use it to store entities in a map, window.localStorage and window.sessionStorage.

Note: this implementation supports cache. It is mainly designed for using on the client. If you don't want, you can pass a dummy EntityCache to MapStorageAccess.by.
