This method should move back out to the OntologiesPage class.  Instead, the OntologiesTable widget should implement the following two interfaces:

1. HasValue<TreeMap<String, OntologySummaryBean>>
2. HasSelectionHandlers<OntologySummaryBean>

The idea is that the widget is capable of displaying the Map of ontologies *and* users are able to select one of them, causing a selection event to be fired.  

The Page should call setValue() on the OntologiesWidget to display the list of ontologies.  It should also add a selection handler to the OntologiesWidget to receive notifications when the user changes a selection.

For an example of this see *OntologyEditorTier.java*.
