1.11 00:57:51 A fix for problem reported by Nesime.
Simulatenous processing of the box and enqueing of the tuples caused
statistics to observe some weird numbers.

Statistics collection is finally functional. Scheduler collects per-box
cost as specified in the creation parameters of Stats object in AuroraNode
Nesime (and whoever else plans on using the stats), ask me if you want to
know how to use it.
Selectivity stats maintenance is on the way.
Note that records are not being removed when a box moves, so it will collect
0-s while away.

Several bug fixes.
QueueListners are now properly changed from input listeners to internal
listeners and vice-versa. That should be the proper rewrite replacing
Magda's fix (Magda, thank you for the quick fix! :)
A subtle bug with scheduler not waking up occasionally should be fixed now.
As far as I understand it was an interesting combination of two different
bugs, where each could cause similar behavior involving a non-waking up
scheduler.
Please report to me if scheduler fails to wake up during your runs. This
bug was somewhat non-determenistic and difficult to observe.
2004/09/30 mbalazin Added a reverse seek iterator so we can examine a queue from either end.
2004/09/28 mbalazin Fixed bug in avail() method for seekIterator. Was always returning true.. but we cannot seek anything past the current enqueue point.
2004/09/24 yna Moved most of the Aurora code into the Borealis namespace. There are still a few things in util/ that aren't
used that need to be moved.....
2004/08/24 bb Removed DOXYGEN_SKIP to clean up a doxygen warning.
2004/08/17 anurag Connection Point and supporting files added

drainSubNetwork now works (still disabled by default).
chokeSubNetwork works much better with border cases being taken care of.
TupleQueueListeners are now disabled/enabled properly.
A few subtle bugs fixed.
2004/06/30 yna Fixed scheduler's removeBoxes, fixed TupleQueueListener's notify method to use try_lock, working movebox_test demo.
2004/04/14 mbalazin New dir structure
