=head1 NAME

GO::Model::GraphNodeInstance  - a graph node located in a tree

=head1 SYNOPSIS

  $it = $graph->create_iterator;
  # returns a GO::Model::GraphIterator object

  while (my $ni = $it->next_node_instance) {
    $depth = $ni->depth;
    $term = $ni->term;
    $reltype = $ni->parent_rel->type;
    printf
      "%s %8s Term = %s (%s)  // depth=%d\n",
          "----" x $depth,
          $reltype,
	  $term->name,
	  $term->public_acc,
          $depth;
  }
