the class ThemeConfiguration method configureSelectedSortHeaderStyle.

/**
 * This method is used to register styles for the selected sort header
 * layer. It will register the {@link IStyle} and the {@link ICellPainter}
 * for both sort states which cause adding the following labels to the
 * configuration label stack of a cell:
 * <ul>
 * <li>DefaultSortConfiguration.SORT_DOWN_CONFIG_TYPE</li>
 * <li>DefaultSortConfiguration.SORT_UP_CONFIG_TYPE</li>
 * </ul>
 * Typically the {@link ICellPainter} itself takes care about the sort
 * state. If this needs to be handled differently, this method needs to be
 * overridden.
 *
 * @param configRegistry
 *            The IConfigRegistry that is used by the NatTable instance to
 *            which the style configuration should be applied to.
