create-custom-fns clj

(create-custom-fns custom time-opts)

create custom functions

(create-custom-fns [{:keys [:bench.stats.lag :bench.stats.time] :sample 10 :aggregate :max}] {:order :desc :key :start}) => (contains {:bench.stats.lag fn? :bench.stats.time fn?})

create-merge-fn clj

(create-merge-fn {:keys [sample aggregate none] :as m} time-opts)

creates a merge function
