Is the smallest transaction unit a property of the commodity, or of the account?
Clark Jones mentioned the case of the mill for US Dollars - do you need some
accounts that count mills and others that count cents?
   What if I were a fruit vendor who bought raspberries from pickers by the
kilogram, and retailed them by the pint?
   I suggest that each account should define its commodity and an arbitrary
rational conversion factor from counted units to the commodity.  gnc_commodity
could contain a default conversion (1/100 for USD).
