/** This class visually illustrates a StringTemplate instance including
 *  the chunks (text + expressions) and the attributes table.  It correctly
 *  handles nested templates and so on.  A prototype really, but may prove
 *  useful for debugging StringTemplate applications.  Use it like this:
 *
 *   *  StringTemplate st = ...;
 *  StringTemplateTreeView viz =
 *  		new StringTemplateTreeView("sample",st);
 *  viz.setVisible(true);
 *
