src : sum_poly.cc
Added the routine `sum_poly_alt' that computes the symbolic sum of the
values of a polynomial using Levy's algorithm, which is based on
At the moment, it is not called by other functions.
This version appears to slow down `make check' a little,
but seems to be much faster than `sum_poly' when called to compute
sums like `sum(a,1,n,a^100)'
