Document use of Cronic or alternatives

[tgharold]

It's probably more important to capture error output so that the error messages can be emailed to a system administrator. The "cron" system already sends an email to the owner of the cron job with the regular output from the script.

Will need to create a temporary file and fill it with error messages and other informational information as the script runs, so that it can be emailed during clean-up after a fatal error occurs.

This should be handled instead by something like Cronic, Shush, or Cronwrap. I need to add that to the the README or INSTALL
