  22. * @param {Function} iteratee - A truth test to apply to each item in `coll`.
  23. * The `iteratee` is passed a `callback(err, truthValue)`, which must be called
  24. * with a boolean argument once it has completed. Invoked with (item, callback).

  26. * `iteratee` functions have finished. Invoked with (err, results).
