   * Delegate used to provide new implementation of a select few methods of {@link MenuInflater}
   * <p/>
   * Through the layoutlib_create tool, the original  methods of MenuInflater have been
   * replaced by calls to methods of the same name in this delegate class.
   * <p/>
   * The main purpose of the class is to get the view key from the menu xml parser and add it to
   * the menu item. The view key is used by the IDE to match the individual view elements to the
   * corresponding xml tag in the menu/layout file.
   * <p/>
   * For Menus, the views may be reused and the {@link MenuItem} is a better object to hold the
   * view key than the {@link MenuView.ItemView}. At the time of computation of the rest of {@link
   * ViewInfo}, we check the corresponding view key in the menu item for the view and add it
