[tor-reports] Philipp's May 2015

[Philipp Winter]

- Attended a censorship measurement workshop at Stony Brook University [0].

- I had more time to hack on sybilhunter.  I added an analysis method
  that makes use of vantage point trees to efficiently find nearest
  neighbours for a given relay descriptor [1].  I also added code to
  visualise similarities [2].

- I worked on a HotPETs talk proposal [3] that summarises our Sybil
  detection work.  We will give the talk next month.
