- now the call of 'setId($id)' doesn't break the fluent interface. Now you can use for example: $person->setId(1)->setName('MyName');
- Specifying an id in the constructor didn't work as expected The call new Person(array('id' => 1)) caused setting both 'id' = 1 and '_id' = auto generated ObjectId and therefore was not equal to $person->setId(1) It's now fixed.
