*
* $importer = the contact_record (joined to user_record) of the local user who owns this relationship.
* It is this person's stuff that is going to be updated.
* $contact = the person who is sending us stuff. If not set, we MAY be processing a "follow" activity
* from an external network and MAY create an appropriate contact record. Otherwise, we MUST
* have a contact record.
* $hub = should we find a hub declation in the feed, pass it back to our calling process, who might (or
* might not) try and subscribe to it.
* $datedir sorts in reverse order
* $pass - by default ($pass = 0) we cannot guarantee that a parent item has been
* imported prior to its children being seen in the stream unless we are certain
* of how the feed is arranged/ordered.
* With $pass = 1, we only pull parent items out of the stream.
* With $pass = 2, we only pull children (comments/likes).
*
* So running this twice, first with pass 1 and then with pass 2 will do the right
* thing regardless of feed ordering. This won't be adequate in a fully-threaded
* model where comments can have sub-threads. That would require some massive sorting
* to get all the feed items into a mostly linear ordering, and might still require
* recursion.
