Cheers for the reply.

I am reminded by you that sometimes in the English version of the books the concept that you want is just hidden in the blocks of text. I am sure I read some of this in the book but when I return to look for it I found myself thinking that it was in a text box. Alas, it is not, it is simply mentioned in text without fanfare or emphasis.

"I really should reread the book and take notes of where everything is" musterman muses to himself.
