In Example #2 MongoCollection::group(), the $condition array should be updated to:

$condition = array('condition' => array("a" => array( '$gt' => 1)));

instead of:

$condition = array("a" => array( '$gt' => 1));

As of 1.2.11+ there is a depreciation notice thrown since $options has been 
modified.
