How to use the batch-cluster.setLogger function in batch-cluster

import { Deferred, Logger, setLogger } from "batch-cluster"
import { createHash } from "crypto"
import * as fse from "fs-extra"
import { tmpdir } from "os"
import { join } from "path"
import { env } from "process"

import { orElse } from "./Maybe"

const chai = require("chai")
chai.use(require("chai-as-promised"))
chai.use(require("chai-subset"))

// Tests should be quiet unless LOG is set
setLogger(
  Logger.withLevels(
    Logger.withTimestamps(
      Logger.filterLevels(
        {
          trace: console.log,
          debug: console.log,
          info: console.log,
          warn: console.warn,
          error: console.error
        },
        orElse(env.LOG as any, "error")
      )
    )
  )
)
