Atoms of an expression

[Dr. Vassilis S. Vassiliadis]

How is it possible to get GiNaC to yield all the 
atoms occuring in an expression? (i.e. return a
list of all the leaves of the expression tree).

This is of interest in the generation of sparse 
jacobian / hessian matrices as one example of 
applications.
