Twig Renderable Gui Builder using Class derived types
This project is an experimental work in progress
Usages:
$productMeta = $this->factory->create(SidebarListSubMenu::getType())->setLabel('Product Meta')->setIcon('icon-folder'); // creates link before before new list?
$productMeta->addLink('Categories', 'foo', null, []);
$productMeta->add($this->factory->create(Link::getType())->setLabel('Attributes'));
$productMeta->add($this->factory->create(Link::getType())->setLabel('Products'));
$menu->add($productMeta);
