    set_materialized_path
        Probably shouldn't mess with this. It's used by "insert" and
        "delete".

  OVERRIDDEN METHODS
    insert
        Sets the materialized path.

    update
        Updates which change the parent of a record necessarily cascade
        through all their children and grandchildren to recompute and set
        their new materialized paths. E.g., given this tree–

                          1
                          |
                          3
                         / \
                       12   8
                      /\    /\

You get paths including B<1/3/12/13> and B<1/3/4>. Let's say we change record 3's parent from 1 to 2E<ndash>
