/**
 * This class keeps the selection of a (feature) {@link JTable} synchronized

 * implementing:
 * <ul>
 * <li>a {@link PropertyChangeListener} which listens to the
 * {@link StyledLayerSelectionModel} and accordingly changes the {@link JTable}
 * selection</li>
 * <li>a {@link ListSelectionListener} which listens to the {@link JTable} and
 * accordingly changes the {@link StyledLayerSelectionModel} selection</li>
 * </ul>
 * After creating, the instance of this synchronizer must be added as listener
 * to both, the {@link StyledLayerSelectionModel} and the table's
 * {@link ListSelectionModel}.
