OSID - osid.mapping.MapNotificationSession Service Interface Definition

Interface	osid.mapping.MapNotificationSession
Implements	`osid.OsidSession`
Description	This session defines methods to receive notifications on adds/changes to `Map` objects. This session is intended for consumers needing to synchronize their state with this service without the use of polling. Notifications are cancelled when this session is closed.
Method	canRegisterForMapNotifications
