If I am not mistaken, the value refers to the base-two logarithm of the 
reciprocal duration of a note.  (I think it's the reciprocal, but I 
might have it backwards.)

So, -3 = maxima, -2 = longa, -1 = breve, 0 = whole, 1 = half, 2 = 
quarter, etc.

That means setting the usable-duration-logs list to just '(0) means it 
can only use the whole rest symbol for the multi-measure rest.
