* @discussion If asyncDataFetching is enabled, the `ASTableView` will fetch data through `tableView:numberOfRowsInSection:` and
* `tableView:nodeForRowAtIndexPath:` in async mode from background thread. Otherwise, the methods will be invoked synchronically
* from calling thread.
* Enabling asyncDataFetching could avoid blocking main thread for `ASCellNode` allocation, which is frequently reported issue for
* large scale data. On another hand, the application code need take the responsibility to avoid data inconsistence. Specifically,
* we will lock the data source through `tableViewLockDataSource`, and unlock it by `tableViewUnlockDataSource` after the data fetching.
* The application should not update the data source while the data source is locked, to keep data consistence.
