bundles/org.eclipse.ui.ide/src/org/eclipse/ui/wizards/newresource/BasicNewGroupResourceWizard.java
* IWorkbenchWizard wizard = new BasicNewGroupResourceWizard();
 * wizard.init(workbench, selection);
 * WizardDialog dialog = new WizardDialog(shell, wizard);
 * dialog.open();
 * </pre>
 * During the call to <code>open</code>, the wizard dialog is presented to the
 * user. When the user hits Finish, a group resource at the user-specified
 * workspace path is created, the dialog closes, and the call to
 * <code>open</code> returns.
 * </p>
