Edward,
I hacked up an awk script that attempts to insert the iterations parameter
if it is not set in SDFDirector or any of the derived classes.

The body of the script looks like:

> /HDFDirector"/ || $0 ~ /PthalesDirector"/) {

Basically, it looks for SDFDirector or its subclasses and the inserts 
the iterations parameter
if it is not already set.

I ran the tests and while there are a number of failures, it is not looking
so bad.

Shall I check in the changed .xml files?

Note that there is an open Kepler bug:
" SDF director iterations parameter default of 0 is unfriendly"
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5546

This change will requires updating documentation in both Ptolemy II and 
Kepler.
