NAME

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

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;
         }
