code: function every(coll, iteratee, callback) {
      return createTester(bool => !bool, res => !res)(eachOf, coll, iteratee, callback)
  }
docs: Returns `true` if every element in `coll` satisfies an async test. If any
  iteratee call returns `false`, the main `callback` is immediately called.

  @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over.
  @param {AsyncFunction} iteratee - An async truth test to apply to each item
  in the collection in parallel.
  The iteratee must complete with a boolean result value.
  Invoked with (item, callback).
  @param {Function} [callback] - A callback which is called after all the
  `iteratee` functions have finished. Result will be either `true` or `false`
  depending on the values of the async tests. Invoked with (err, result).
  @returns {Promise} a promise, if no callback provided
  @example
  
  async.every(['file1','file2','file3'], function(filePath, callback) {
  fs.access(filePath, function(err) {
  callback(null, !err)
  });
  }, function(err, result) {
  // if result is true then every file exists
  });
