* 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

* 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
