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