NAME

         GO::Model::GraphIterator - wraps GO::Model::GraphIterator

SYNOPSIS

DESCRIPTION

       This is a hack.  It wraps GO::Model::GraphIterator and provides a tree like iteration,
       rather than a graph-like iteration.

       This is done by giving TreeIterator a template array.

       The array looks like this :

       [ [3674, 'isa', 3673], [9277, 'isa', 5618] ]

       3674 is selected iff it is the child of 3673.  9277 is selected iff it is the child of
       5618.
