VOID??  I'm going to presume that this should have been bool.
Otherwise, thanks.  That was they syntax I couldn't figure out from the 
docs.

And, yeah.  That's what it looks like.  My find code was wrong, because 
it should have referenced the node, so what I need to do is move the cod 
into the node class.  But it was the syntax of defining the opBinary 
specialization that was hanging me up.  (For some reason I have a hard 
time wrapping my mind around template code.)
