Class MENU does not work with multi-levels Menus

[maxleistner]

If a Menu is called all menu items are delivered on the same level, even if in the WordPress Admin the Menu is sorted like this f.e.:

• Menu Item 1
  -- Menu Item 1.1
  -- Menu Item 1.2
• Menu Item 2
• Menut Item 3

A debug delivers any array with all items on the same level. Only the parent_item id is saved within the object.
It would be perfect if the Class Menu would deliver the submenu items as sub-items like it is done in the normal WordPress logic or Timber-Logic.

There might be a hint how this can be done here: https://github.com/corcel/corcel#multi-levels-menus

The complete behavior of menus by now relies heavily on corcel and doesn't quite work the way it should. I plan to give it a complete rewrite in the next weeks.
