graph

  Usage   - my $terms = $obj_handler->graph->get_all_terms;
  Synonym - g
  Synonym - ontology
  Returns - GO::Model::Graph object
  Args    -

as files are parsed, objects are created; depending on what kind of datatype is being parsed, the classes of the created objects will be different - eg GO::Model::Term, GO::Model::Association etc

the way to access all of these is through the top level graph object

eg

  $parser = GO::Parser->new({handler=>'obj'});
  $parser->parse(@files);
  my $graph = $parser->graph;
