            The main difference between datamenu and automenu is that automenu (By
            virtue of it generating the menu automatically) doesn't know ahead of
            time what it's children are.

            Because of that, this entire first part is dedicated to looping
            through *all* pages and filtering out the ones that are not
            children of the current node.

            We also have to take special care with the "/" page as this could
            result in infinite recursion.
