/**
 * Presents an {@code URIChooser} for selecting a directory and loads the
 * selected URI into an empty view. If no empty view is available, a new view is
 * created.
 * <p>
 * This action is called when the user selects the Open Directory item in the
 * File menu. The menu item is automatically created by the application.
 * <p>
 * If you want this behavior in your application, you have to create it
 * and put it in your {@code ApplicationModel} in method
 * {@link ApplicationModel#initApplication}.
 * <p>
 * This action is designed for applications which automatically
 * create a new view for each opened file. This action goes together with
 * {@link NewFileAction}, {@link OpenFileAction} and {@link CloseFileAction}.
 * This action should not be used together with {@link LoadFileAction}.
