Represents the Jena {@link Model} and the Clerezza {@link Graph} or{@link MGraph}. It also provide access to the {@link JenaGraphAdaptor}so that this component can add parsed data to {@link Graph}s created by calls to {@link SingleTdbDatasetTcProvider#createGraph(UriRef,TripleCollection)}. @author Rupert Westenthaler
