.IX Header "DESCRIPTION"
This is a hack.  It wraps GO::Model::GraphIterator and provides
a tree like iteration, rather than a graph-like iteration.
.PP
This is done by giving TreeIterator a template array.
.PP
The array looks like this :
.PP
[
[3674, 'isa', 3673],
[9277, 'isa', 5618]
]
.PP
3674 is selected iff it is the child of 3673.  
9277 is selected iff it is the child of 5618.
