Hello Tor, hello world!

Below you'll find the highlights of Tor metrics team work done in
August 2016.

On behalf of the Tor metrics team,
Karsten


Helped with the transition from bridge authority Tonga to Bifroest
[1], including: updating CollecTor to sanitize Bifroest's bridge
descriptor tarballs; updating Metrics to count running bridges from
both Tonga and Bifroest [2]; and continually graphing the transition
progress [3].
