Gotcha.

Might as well just go with these two dictionary methods for now.
We can add more as needed.

Cool. Any thought's on how we add tests for these?  All the front ends
need testing and I am at a loss as to how to actually test them.

We could try installing seomthing like:

  https://docs.pylonsproject.org/projects/webtest/en/latest/webtest.html

and I think that could work with cgi, roundup-server, wsgi but I would
prefer something that works without having to install a new library.
