-/**
- * 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.
- *

+/**

+ * 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.

+ *
