I wrote an interval class for cmucl long ago. Handled all of the
basic operations and some of the special functions too. It's now
somewhat coupled to cmucl, but the arithmetic parts could come out
easily.
However, it didn't really do complete interval arithmetic because it
didn't round numbers up and down when computing interval bounds. That
was a problem for cmucl when you could mix numbers of different
types. But maxima basically only supports 1 (HW) floating-point type,
so this is much easier.

I think orthopoly is a much better name.
