+ *
+ * This plugin lists all the events contained in the current time interval
+ * in a list.
+ *
+ * This plugin adds a Events Viewer functionnality to Linux TraceToolkit
+ * GUI when this plugin is loaded. The init and destroy functions add the
+ * viewer's insertion menu item and toolbar icon by calling viewer.h's
+ * API functions. Then, when a viewer's object is created, the constructor
+ * creates ans register through API functions what is needed to interact
+ * with the lttvwindow.
