   5  * \brief Graphical plugin for showing control flow of a trace.
   6  *
   7  * This plugin adds a Control Flow Viewer functionnality to Linux TraceToolkit
   8  * GUI when this plugin is loaded. The init and destroy functions add the
   9  * viewer's insertion menu item and toolbar icon by calling gtkTraceSet's
  10  * API functions. Then, when a viewer's object is created, the constructor
  11  * creates ans register through API functions what is needed to interact
  12  * with the TraceSet window.
  13  *
  14  * This plugin uses the gdk library to draw the events and gtk to interact
  15  * with the user.
