This is a follow-on task to http://www.google-melange.com/gci/task/view/google/gci2013/4812355431038976

Basically, set up the code coverage report so that it is generated at least once a day.  This requires an account on our brlcad.org web server.  Set up the update as user 'www' or user 'brlcad' daily cron job.  Make sure the cron job either sends output to a log file or has no output (any output results in e-mails).

We'll hook it into jenkins/buildbot later so that it updates on commit, but it'll be useful to have the command or script known via cron.
