Draft: (paused) distance result precomputation
Outputs the result of the distance computation for all identities in a json file in the form:
{"block":"0x432a43af2b2aef4ab33ac9a4323b1f084b86388bc46744f7ce5936a5bbcd07f6","results":{"4":4,"1":4,"3":4,"2":4},"referees":4}
This file can be computed regularly and served directly through nginx. This would allow the clients to have a recent estimate of the distance result before requesting evaluation.
