Comment 3 for bug 954310

Updated branch pushed to:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/collab/berick/ou-visibility-and-sorting

Feature one described above has not changed. Feature two now supports free-form org unit hierarchies for display instead of being limited to intra-parent (sibling) sorting. Instead of adding a column to actor.org_unit, the new implementation creates 2 new tables, a tree table and a tree node table, which implements a generic org unit re-tree-ification structure.
