Union of named graphs is really a feature of the storage and not as 
uniformly treated as I would like.

For an in-memory dataset, this works:

    Graph g = GraphView.createNamedGraph(dsg, Quad.unionGraph) ;
    Model m = ModelFactory.createModelForGraph(g) ;

(latest version)

It'll work on on any dataset, maybe not optimally though (but not bad 
either).
