+ * Class: mxGraphSelectionModel
+ *
+ * Implements the selection model for a graph. Here is a listener that handles
+ * all removed selection cells.
+ * 
+ * (code)
+ * graph.getSelectionModel().addListener(mxEvent.CHANGE, function(sender, evt)
+ * {
+ *   var cells = evt.getProperty('added');
+ *   
+ *   for (var i = 0; i < cells.length; i++)
+ *   {
+ *     // Handle cells[i]...
+ *   }
+ * });
+ * (end)
+ * 
+ * Event: mxEvent.UNDO
+ * 
+ * Fires after the selection was changed in <changeSelection>. The
+ * <code>edit</code> property contains the <mxUndoableEdit> which contains the
+ * <mxSelectionChange>.
+ * 
+ * Event: mxEvent.CHANGE
+ * 
+ * Fires after the selection changes by executing an <mxSelectionChange>. The
+ * <code>added</code> and <code>removed</code> properties contain arrays of
+ * cells that have been added to or removed from the selection, respectively.
+ * 
+ * Constructor: mxGraphSelectionModel
+ *
+ * Constructs a new graph selection model for the given <mxGraph>.
+ * 
+ * Parameters:
