There is a fudge to iterate over diseases, which should be improved.

This configuration works with EWS-EpiModel git commit 631e3520. This can handle multiple diseases but only one region. Output directories are <job-directory>/<region>/<disease>/<output>

For now, one set for production, called 'live', and a second for development 'ewsdev'. Advise any clone of the repo creates its own set of these config files. This resolves the issue of having local uncommitted modifications to config files.
