+/**
+ * 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
