  25  * \brief Graphical plugin for showing control flow of a trace.
  26  *
  27  * This plugin adds a Control Flow Viewer functionnality to Linux TraceToolkit
  28  * GUI when this plugin is loaded. The init and destroy functions add the
  29  * viewer's insertion menu item and toolbar icon by calling viewer.h's
  30  * API functions. Then, when a viewer's object is created, the constructor
  31  * creates ans register through API functions what is needed to interact
  32  * with the TraceSet window.
  33  *
  34  * This plugin uses the gdk library to draw the events and gtk to interact
  35  * with the user.
  36  *
