CodeIgniter MongoDB Library

This is a query builder inspired CodeIgniter library to integrate a MongoDB database into your application.

Using with CodeIgniter:

Update the config file -- mongodb.php to your /application/config folder.
Autoload the library or include it in one of your controllers at run time.
Interact with the database using many of the active record functions that CodeIgniter provides.

$this->mongo_db ->where_gte('age', 18) ->where(array( 'country' => 'UK', 'like_whisky' => TRUE )) ->get('people');

The result will be an object containing matching documents.
