  592. * - We assume the database is well-formed - no stranded/dangling folders, all folders in heirarchy owned
  593. * by the same person, each user only has 1 inventory heirarchy
  594. * - The returned list is not ordered, instead of breadth-first ordered
  595. There are basically 2 usage cases for getFolderHeirarchy:
  596. 1) Getting the user's entire inventory heirarchy when they log in
  597. 2) Finding a subfolder heirarchy to delete when emptying the trash.
  598. This implementation will pull all inventory folders from the database, and then prune away any folder that
  599. is not part of the requested sub-heirarchy. The theory is that it is cheaper to make 1 request from the
  600. database than to make n requests. This pays off only if requested heirarchy is large.
  601. By making this choice, we are making the worst case better at the cost of making the best case worse.
  602. This way is generally better because we don't have to rebuild the connection/sql query per subfolder,
  603. even if we end up getting more data from the SQL server than we need.
