The worst possible answer would be to supply large amounts of gratuitous detail (of exactly the kind that you can Google for) without indicating any conceptual grasp of what is going on.
I always supply large amounts of gratuitous detail without indicating any conceptual grasp of what is going on. Stream of unending conscience and all that, you know. ;) Obviously you have not paid attention to any of my posts for the past 6 years or however long I have been posting them as. If I googled it would have been word for word and explained it better than I explained it.
But I have been branded as a Googler, and I hate Google with a passion and do not want to use it. I have stated that before, and I am only repeating myself yet again to someone who obviously did not pay attention to my previous posts. So you and Peter can have your reality on that. I don't care what you two think anymore.
