I would write little wrapper functions that check the pointer, and if
it's NULL, return None instead of the dereferenced value.
To illustrate:
object get_age(FaceObject &f) { return f.getAge() ?
object(*f.getAge()) : object();}
...
class_<FaceObject, boost::noncopyable>(...).add_property("age", get_age);
Thus, if the pointer is initialized, the value pointed to will be
returned, and if not, None.
