Source code for a site that used to show statistical analysis of M+ in WoW.
For a simpler version of the same idea, you can also refer this website https://github.com/alcaras/mplus-analysis
This code is what the site is currently running.
It's set up to run as an App Engine instance that runs a cron job that updates data and generates static HTML, writing directly to a Cloud Storage instance. A bit strange, but it scales quite nicely since it only ever serves static HTML pages externally.
