Surely, the cleanest way to handle continued fractions would be to modify
simplus and friends. Then, for example, cf(1,2) + cf(3,4) => cf(4,1,3).
(Currently, cf([1,2] + [3,4]) => [4,1,3].) Reworking Maxima's arithmetic
simplification functions would be a good thing (they are slow and
inflexible), but it's a great deal of work.
