Comment 3 for bug 1185524

Unfortunately, you can't simply assume that the top of the org tree will have an ID of '1'.

Additionally, as coded, this will be useless for a significant set of existing Evergreen users where they want to check more broadly than a branch, but not everywhere. Instead of having an all-or-nothing choice, I recommend allowing the selection of an org unit depth as the YAOUS, and then use the existing org_unit_ancestor_at_depth() method available in OpenILS::Application::AppUtils to get the appropriate org unit id.

I feel relatively strongly about this, so I'm setting the bug to incomplete.
