49	* <li>a {@link PropertyChangeListener} which listens to the
50	* {@link StyledLayerSelectionModel} and accordingly changes the {@link JTable}

52	* <li>a {@link ListSelectionListener} which listens to the {@link JTable} and
53	* accordingly changes the {@link StyledLayerSelectionModel} selection</li>

55	* After creating, the instance of this synchronizer must be added as listener
56	* to both, the {@link StyledLayerSelectionModel} and the table's
57	* {@link ListSelectionModel}.
