UpdateDataObject might should return initialized hierarchy collections.

[jamoore]

Currently updateDataObject(IObject,...) returns a null for the parent or children links because the collection was never initialized.

To do this in a generic way, the Hierarchy class should provide a way to simply walk (not query) the hierarchy structure.

Perhaps the walk could be configured by the collections which are not null in the IObject argument, e.g.:

 if Project.DATASETLINKS is null, leave null, else
   initialize; and
   if Project.Dataset.IMAGELINKS is null, leave null, else
   initialize; and
     ...

This came up concretely in Shoola.

1. call IPojos.createObject() with an ImageAnnotation
2. get the ImageAnnotation back with an attached Image
3. pass that Image up to the agent layer
4. Image.getName() throws an unloaded exception.

The Image which was passed into the createObject call should have also been fetched.
