+ * <li>Set view extension class to\r
+ * <code>org.simantics.browsing.ui.swt.ModelledView:configurationURI=ConfigURI</code>\r
+ * , where ConfigURI is the URI of your view configuration.</li>\r
+ * <li>Extend this class and override at least {@link #configurationURI()} to\r

+ * extension class to the created class.</li>\r
