CodeIgniter 3 to 4 Upgrade Helper

@GreTaurus Implement the feature and send a pull request.

Or you can manually upgrade only the class that is using group_start() to CI4.
See https://codeigniter4.github.io/CodeIgnit...y-grouping

You are already using CI4, so you can use it without the upgrade helper.
The upgrade helper is just a wrapper for CI4.

Sorry for dump question but i have a code 
$this->db->count_all_results('cms_news');
and get a errorr
Call to undefined method Kenjis\CI3Compatible\Database\CI_DB::count_all_results() 

How can i use countAllResults like CI4 . If your helper doesn't have that function, how can i extend it? . Can i use both CI3 and CI4 syntax in the same model ?
