I was just repeating myself here, I guess.  I was basically saying it would
be nice to be able to adjust big units (like months) backwards by small
units (like days).

I will look at your examples and see if I can see how to accomplish what I
want to do with them.  Also, I undersand why something like the month
iterator cannot be a model of Biderectional Iterator (as it would violate
the semantic meaning in some cases), but is there a reason why the date
iterator itself is not bidrectional?
