docs: Takes the path to a JSON file declaring experiment specifications, and
      modifies the experiments stored in redis to match the spec.
  
      A spec looks like this:
      {
         "experiment 1": ["choice 1", "choice 2", "choice 3"],
         "experiment 2": ["choice 1", "choice 2"]
      }
