Paulo and David, thanks for the positive comments.
David, in the past, for personal reasons I did not want to use my real name: Mark Nadler. So,
I scrambled it to Karm (i.e. Mark) Redland (i.e. almost Nadler). I now have no reason to do this.
However, I have used Karm Redland for a long tinme and choose to continue using it.
