True, but you'd be surprised. :) And I get more than a couple of emails 
occasionally from people for whom tellico is the first program they've ever 
tried to compile!

I'm compiling with your patch right now.

Might be easier now since I refactored the comparisons into a separate 
class. Just subclass ListViewComparison and add the constructor to the 
factory method there.

This is the case where you wanted to sort by the first field mentioned in 
the dependent field, then the 2nd, etc. right? Rather than sorting by the 
combined string value? I'm trying to figure out a case where that might be 
different than what a user might expect naturally. So far, I can't think of 
an example. :)
