Hi Jaoquin,
Thanks. I found the poly download actually it is there asl_1.0.42. A lot 
more stuff than the header I first looked at.
<http://stlab.adobe.com/iterator_8hpp_source.html>

Most of that was built on iterator_facade. It will take me some time but 
I'll see what I can do with it. This is as much to learn as to use it in 
my app.

Best, Dan.
