...and hopefully some other functions too? :-)

I read that back in 1997. (Yes, that's how old it is.) I had trouble 
understanding it back then, and having reread it a few times since then, 
I still have trouble comprehending it.

I think essentially wavelets are just too complicated to understand. So 
I'll stick with my original approach...
