/**
* This script checks the integrity of the add-on download and updateping counts
* obtained from parsing logs.
*
* The script checks a number of popular add-ons for several things:
* - Does the download count from 2 days ago exist?
* - If so, is there a difference of greater or less than 50% from the
* previous 2 counts?
* - If it's Saturday, does the update ping count from Wednesday exist?
* - If so, is there a difference of greater or less than 50% from the
* previous 2 counts?
*
* Download counter runs every night and can go into the next morning.
* Accounting for a potential 24 hour log delay from the CDN, this is checked
* 2 days after.
*
* Update ping counter is only run on Thursday nights and can go into Friday
* mornings. Accounting for a potential 24 hour log delay from the CDN, this
* will be checked on Saturdays.
