 * <code>NodeDialog</code> for the "StringMatcher" Node.
 * Used to match a set of strings against a column in the input table. All input columns are preserved, but the matches are appended to the table.
 *
 * This node dialog derives from {@link DefaultNodeSettingsPane} which allows
 * creation of a simple dialog with standard components. If you need a more 
 * complex dialog please derive directly from 
 * {@link org.knime.core.node.NodeDialogPane}.
