Subject: [PATCH] callbackNextTick method added to API

Sometimes an async function needs tor return  a sync result. For the sake of consistency of async flow; we need to call the callback function wrapped in a nextTick block. This new method simplifys this effort.

Example:
```js
function asyncFn (other_arguments, callback) {
  if (cached_result) {
    return async.callbackNextTick(callback, cached_result);
  }
  some_async_call(some_arguments, callback);
}
```
