Detailed Description
The setup is that you have a db containing a collection with tf messages, in which each message has a metadata field named 'stamp', that equals the tf timestamp (this could be generated, e.g., with bag_to_db followed by add_metadata). Given such a collection, this class allows querying for a transform as with tf::TransformListener::lookupTransform, except this is deterministic with no dependency on network state or message queues.
