// Class that saves not responded(unread) notifications.
// Unread notifications are saved in open_notifications.xml in SL account folder
//
// Notifications that should be saved(if unread) are marked with persist="true" in notifications.xml
// Notifications using functor responders are saved automatically (see llviewermessage.cpp
// lure_callback_reg for example).
// Notifications using object responders(LLOfferInfo) need additional tuning. Responder object should
// be a) serializable(implement LLNotificationResponderInterface),
// b) registered with LLResponderRegistry (found in llnotificationstorage.cpp).
