* @param {Function} [callback] - A callback which is called after all the
* `iteratee` functions have finished. Result is the reduced value. Invoked with
* (err, result).
* @example
*
* async.reduce([1,2,3], 0, function(memo, item, callback) {
*     // pointless async:
*     process.nextTick(function() {
*         callback(null, memo + item)
*     });
