 * A QWidget that provides a console for executing Javascript commands. Creating
 * a JS console is easy, as you can see below:
 *
 * <pre>
 *   KJS::Object global( new KJS::ObjectImp() );
 *   KJS::Interpreter *js = new KJS::Interpreter( global );
 *   KJSEmbed::JSConsoleWidget *win = new KJSEmbed::JSConsoleWidget( js );
 *   win->addBindings( js->globalExec(), global );
 * </pre>
 *
 * This example creates a console for a JS interpreter and adds a print function
 * to the interpreter.
