[GiNaC-list] internal representation of expressions

[Felipe Bordeu]

Hello,

I'm trying to debug a program, and the problems is that the terms in a 
sum are not ordered in the same way in every run.
for example :
1 run :  A+B+C gives A+B+C
2 run :  A+B+C gives C+B+A
...

I know that the 2 expressions are equal but I will like GiNaC to 
represent the expression always in the same way.

It's only for debugging so I don't care about performance.

Thanks
Felipe
