This is just a suggestion, but perhaps it would make sense at some
point to subdivide the algebra code somewhat?  From a more "end user"
perspective, perhaps physics related code could be separate from
chemistry related code?  Or (maybe) integration could be in a package,
and matrix handling in another, and floating point code in still
another?  (I imagine this would have to be expressed in Aldor/Spad as
well.)  I don't know if that could be done - maybe as part of mapping
the inter-relatedness of symbolic mathematics?
