7.7.2.0. variablesSorted
Procedure from library central.lib (see central_lib).

Usage:
variablesSorted();

Return:
ideal, generated by sorted algebra variables

Purpose:
computes the set of algebra variables sorted so that
Cartan variables go first

Note:
This is a heuristics for the computation of the center:
it is better to compute centralizers of Cartan variables first since in this
case we can omit solving the system of equations.

Example:
