Rather than operating on records and record sets, queries against MongoDB will return nested sets
of Document objects. A Document's fields can contain both simple and complex data types
(i.e. arrays) including other Document objects.
After installing MongoDB, you can connect to it as follows:
{{{//app/config/bootstrap/connections.php:
Connections::add('default', array('type' => 'MongoDb', 'database' => 'myDb'));}}}
By default, it will attempt to connect to a Mongo instance running on localhost on port
27017. See __construct() for details on the accepted configuration settings.
