Denis Flaven 7e60a9fce7 Implementation of a new type of ExternalKey attribute: HierarchicalKey. This attribute implements the "nested set" model and is used to define a hierarchy of an arbitrary depth of objects of the same class. With this new feature it is possible to retrieve in one OQL query (and in one sql query as well) all the children of a given organization. ...

I'm still keeping (commented out) some of the traces helpful for debugging the construction of the OQL queries.
