I don't see why you didn't code it straight into freeciv; that patch look
like alot more work than a direct insertion would have taken. :)

Hmm; lots of logaritmic time. I think it can be done in constant time by
limiting maxcost and using a little extra memory. (for our purposes).
Darn, now I'll have to make a patch to prove it... :)
