public function NodeHierarchyChildrenForm::save in Entity Reference Hierarchy 8

Here we are loading the weights/IDs from the values set using the tabledrag in the form() function above.

We then create an object containing only the child weight and hierarchy ID, and write that to the database.

We don't do any checking because no Save button will be shown if no children are present.
