-/**
- * {@link GridSimVisualiser} is the class that represents the main window.
- * used by the visualisation tool. From this window it is possible to
- * start the simulation, run step by step or run it in slow motion. <br>
- * <b>NOTE:</b> This visualisation tool should be used for debugging
- * purposes only. It is useful if you want to evaluate a new allocation
- * policy for example. A real experiment is not meant to have any
- * visualisation features. This interface was initially created for
- * another simulator called PajFit available at <b>http://pajfit.sourceforge.net/</b>.
- *
- * @author Marco A. S. Netto (created this visualisation tool)
- * @author Marcos Dias de Assuncao (modified this class to be
- * used by GridSim.)
- * @since GridSim Turbo Alpha 0.1
- *
- * @see gridsim.GridSim#startGridSimulation(boolean)
- * @see gridsim.GridSim#startGridSimulation()
