A Codeigniter controller to list all functions found in your Controllers and Models and show unused ones.
To use the files, place the application/controllers/code_review.php controller in to your application/controllers folder and place the application/views/code_review.php view file in your application/views/ folder and then open up http://localhost/yourproject/index.php/code_review.php.
This assumes that your application folder is outside your system folder.
