Tree Behaviour > reorder (parent_id NULL)

Just a note to hopefully help others avoid some confusion ...

When using the Tree Behaviour, the table should be setup such that it
allows NULL, with it being the default. I know the
http://book.cakephp.org/view/228/Basic-Usage page shows the SQL as
such; however, I have this crazy habit of not allowing null if it
doesn't have to be.
The docs don't clearly state it must be null, so figured it would be
ok. However, after getting frustrated with the `reorder()` function, I
finally discovered that parent_id can't be '0', but 'null' if it's at
the top.
