Configure codeigniter-restserver for use with Ember.js

Configure codeigniter-restserver for use with Ember.js

First off you need to modify application/config/rest.php
```
$config['rest_default_format'] = 'json';
```
This will ensure that when your api call is made the server will return json without an additional segment.

You must then create an api controller that will return your codeigniter model in the correct format for Ember.js
```
<?php
require(APPPATH.'/libraries/REST_Controller.php');
 
class Api extends REST_Controller
{
   public function index_get()
    {
        $array = array(
        	'yourEmberModel' => $this->db->get('menu')->result() // assign your CodeIgniter model to an array with name yourEmberModel
        	);
        $this->response($array ); // pass this array to the restserver rather than the defaul model
    }
}
```
Now when you visit localhost.com/index.php/api you will have the json returned in correct format for use with Ember.js
```
{
yourEmberModel: [
  {
  id: "1",
  menu_section: "Mic dejun",
  section_order: "1",
  item_name: "Kinder Smoothie",
  weight: "350 ml",
  price: "14",
  ingredients: "lapte de migdale, polen crud, ananas, calse deshid"
  },
  ...
}
```
