Michael T,
Thanks for that new to me, information. Knowledge makes us better. We gain understanding. You know your history -must be a history teacher. I had a great one in college. Dr. Wolf, never forget him. He made me realize that I was capable of better work than I had done up to then. He helped me develop a more analytical mind.  His course was the Civil War up to WWII. The course began with 25students and ended with 5 of us. He was dyn-o-mite!
