"""
This script asks cdash to give it a summary of all of the failing tests
on the Nightly (master) and Nightly (next) section.
It presents the tests ranked by the number
of failing machines. From this view you can more easily see what is in
the greatest need of fixing.
The script also scrapes the dashboard with a list of expected submissions and
generates a list of missing ones.
