template<class T>

QDataStream& operator<<	(	QDataStream &	stream,
		TrapperVector< T > &	t
	)

Todo: But a problem with this approach might be that the endian awareness of QDataStream might be lost, when we don't serialize the types one by one. It might be a problem when moving berkeley dbs around archictures. But berkeley db probably doesn't allow this anyway?
