Modified files:
	src            : sum_poly.cc 

Log message:
	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
	symbolic integration.
	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)'
