Hi Ale,

The mesa philosophy on this one is to give some examples, and then
rely on users to create their own "applications".   So you won't find exactly
what you are looking for, but as you mention, create_zams does something
similar.  Please do me the favor of trying to develop what you need using
create_zams as a template.  I'm happy to help you along with this -- and
then please write up some short notes about how to do it that can be added to
the mesa release for future users.
