[BIOSAL] Thorium - logging?

[George K. Thiruvathukal]

Thanks for reminding me about this! Yes, that's exactly what I was hoping
to find.

I just don't want to be using explicit printf() statements.

See you tomorrow. I am hoping to push out a new version of my
hello_acquaintances today. :) We'll work on the paper tomorrow morning
(among other things).
