/**
* A parser/interpreter for an RDF graph which represents an OWL ontology. The
* consumer interprets triple patterns in the graph to produce the appropriate
* OWLAPI entities, class expressions and axioms. The parser is based on triple
* handlers. A given triple handler handles a specific type of triple. Generally
* speaking this is based on the predicate of a triple, for example, A
* rdfs:subClassOf B is handled by a subClassOf handler. A handler determines if
* it can handle a triple in a streaming mode (i.e. while parsing is taking
* place) or if it can handle a triple after parsing has taken place and the
* complete graph is in memory. Once a handler handles a triple, that triple is
* deemed to have been consumed an is discarded. The parser attempts to consume
* as many triples as possible while streaming parsing is taking place. Whether
* or not a triple can be consumed during parsing is determined by installed
* triple handlers.
