#define LL_LLNOTIFICATIONS_H

/**
 * This system is intended to provide a singleton mechanism for adding
 * notifications to one of an arbitrary set of event channels.
 * 
 * Controlling JIRA: DEV-9061
 *
 * Every notification has (see code for full list):
 *  - a textual name, which is used to look up its template in the XML files
 *  - a payload, which is a block of LLSD
 *  - a channel, which is normally extracted from the XML files but
 *	  can be overridden.
 *  - a timestamp, used to order the notifications
 *  - expiration time -- if nonzero, specifies a time after which the
 *    notification will no longer be valid.
 *  - a callback name and a couple of status bits related to callbacks (see below)
 * 
 * There is a management class called LLNotifications, which is an LLSingleton.
 * The class maintains a collection of all of the notifications received
 * or processed during this session, and also manages the persistence
 * of those notifications that must be persisted.
 * 
 * We also have Channels. A channel is a view on a collection of notifications;
 * The collection is defined by a filter function that controls which
 * notifications are in the channel, and its ordering is controlled by 
 * a comparator. 
 *
 * There is a hierarchy of channels; notifications flow down from
 * the management class (LLNotifications, which itself inherits from
 * The channel base class) to the individual channels.
 * Any change to notifications (add, delete, modify) is 
 * automatically propagated through the channel hierarchy.
 * 
 * We provide methods for adding a new notification, for removing
 * one, and for managing channels. Channels are relatively cheap to construct
 * and maintain, so in general, human interfaces should use channels to
 * select and manage their lists of notifications.
 * 
 * We also maintain a collection of templates that are loaded from the 
 * XML file of template translations. The system supports substitution
 * of named variables from the payload into the XML file.
 * 
 * By default, only the "unknown message" template is built into the system.
 * It is not an error to add a notification that's not found in the 
 * template system, but it is logged.
 *
