[GiNaC-list] Expression order changing

I think it should be possible to create your symbols in a vector and then
use .set_name() to swap around the names of the symbols in such a way that
the symbol that comes at a certain place in the canonical ordering gets
the right name. Bit of an ugly hack though.

Good luck,
Chris
