/**
 *
 * consume_feed - process atom feed and update anything/everything we might need to update
 *
 * $xml = the (atom) feed to consume - RSS isn't as fully supported but may work for simple feeds.
 *
 * $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.
