456 * by the same person, each user only has 1 inventory heirarchy
457 * - The returned list is not ordered, instead of breadth-first ordered
458 There are basically 2 usage cases for getFolderHeirarchy:
459 1) Getting the user's entire inventory heirarchy when they log in
460 2) Finding a subfolder heirarchy to delete when emptying the trash.
461 This implementation will pull all inventory folders from the database, and then prune away any folder that
462 is not part of the requested sub-heirarchy. The theory is that it is cheaper to make 1 request from the
463 database than to make n requests. This pays off only if requested heirarchy is large.
464 By making this choice, we are making the worst case better at the cost of making the best case worse
