Overriding Public Folder In Codeigniter via composer plugin

Hi,
i recently tried my hands on codeigniter composer installer by Kenjis. it had a directory structure like this;
codeigniter/
├── application/
├── composer.json
├── composer.lock
├── public/
│ ├── .htaccess
│ └── index.php
└── vendor/
└── codeigniter/
└── framework/
└── system/

I uploaded it into my www directory and i fired it up. I noticed that before i could actually see the welcome message i had to hada to navigate pass the public folder so i had something like this ; http://localhost/apple/public, before i could actually see the welcome message. Any ideas how to override that?
i want to see the welcome message at http://localhost/apple and not  http://localhost/apple/public.
