Two trips to Google, and one to Wiki in the five minutes it took me to write this.
Udog and Andy, and others who like to delve, are probably who/what I'm hoping to hear from in this context.
I did once try a google search but what I recall now is that I did not find quite what I was looking for. (Though I could stand to do one again to get the basic points back into mind, since now I can't remember what I read. That was a couple months ago and when I did not find what I was looking for, I put it all out of mind.)
There is something I am trying to cipher out which probably requires getting into the finer points of the topic.
