As far as I know, there are no special packages for analytic geometry, but
basic functions and linear algebra stuff are enough, I think. Introducing new
objects may produce more mess than advantages.
In vector calculus code, Maxima represents vectors as lists; "listarith" works
with lists in appropriate way. Vector plotting is already implemented in
draw2d / draw3d.
