/**
* Reserved key to identify the most specific menu link for a given path.
* @section Rendering menus
* Once you have created menus (that contain menu links), you want to render
* them. Drupal provides a block (Drupal\system\Plugin\Block\SystemMenuBlock) to
* do so.
*
* The value of this constant is a hash of the constant name. We use the hash
* so that the reserved key is over 32 characters in length and will not
* collide with allowed menu names:
* However, perhaps you have more advanced needs and you're not satisfied with
* what the menu blocks offer you. If that's the case, you'll want to:
* - Instantiate \Drupal\Core\Menu\MenuTreeParameters, and set its values to
* match your needs. Alternatively, you can use
* MenuLinkTree::getCurrentRouteMenuTreeParameters() to get a typical
* default set of parameters, and then customize them to suit your needs.
* - Call \Drupal\Core\MenuLinkTree::load() with your menu link tree parameters,
* this will return a menu link tree.
* - Pass the menu tree to \Drupal\Core\Menu\MenuLinkTree::transform() to apply
* menu link tree manipulators that transform the tree. You will almost always
* want to apply access checking. The manipulators that you will typically
* need can be found in \Drupal\Core\Menu\DefaultMenuTreeManipulators.
* - Potentially write a custom menu tree manipulator, see
* \Drupal\Core\Menu\DefaultMenuTreeManipulators for examples. This is only
* necessary if you want to do things like adding extra metadata to rendered
* links to display icons next to them.
* - Pass the menu tree to \Drupal\Core\Menu\MenuLinkTree::build(), this will
* build a renderable array.
*
* Combined, that would look like this:
* @code
* sha1('MENU_PREFERRED_LINK') = 1cf698d64d1aa4b83907cf6ed55db3a7f8e92c91
* @endcode
* $menu_tree = \Drupal::menuTree();
* $menu_name = 'my_menu';
*
* // Build the typical default set of menu tree parameters.
* $parameters = $menu_tree->getCurrentRouteMenuTreeParameters($menu_name);
*
* // Load the tree based on this set of parameters.
* $tree = $menu_tree->load($menu_name, $parameters);
*
* // Transform the tree using the manipulators you want.
* $manipulators = array(
* // Only show links that are accessible for the current user.
* array('callable' => 'menu.default_tree_manipulators:checkAccess'),
* // Use the default sorting of menu links.
* array('callable' => 'menu.default_tree_manipulators:generateIndexAndSort'),
* );
* $tree = $menu_tree->transform($tree, $manipulators);
*
* // Finally, build a renderable array from the transformed tree.
* $menu = $menu_tree->build($tree);
*
* @see menu_link_get_preferred()
* $menu_html = drupal_render($menu);
* @endcode
