/**
 * A GUI for editing style maps for the annotation viewer.
 * <p>
 * A style map is an XML document that describes how each kind of output from a Text Analysis Engine
 * is to be displayed in the annotation viewer. Each output type that the user wants to be displayed
 * will have an entry in the style map. Each entry in the style map contains:
 * <ul>
 * <li>The CSS style used to display annotations of that type (for example "background:blue;
 * color:white;" to display white text on a blue background.</li>
 * <li>A label used to identify the annotations in the annotation viewer</li>
 * </ul>
 * <p>
 * To invoke the editor, call the {@link launchEditor(TextAnalysisEngine,String)} method.
