Comment (by pernici):
The algorithm for `newton_sum` is slightly changed with respect to the one
written in BFSS, Lemma 1.
I will change it to the latter form, which is simpler and slightly faster.
In either case there is no inversion, there is reversion though.
Lemma 1 comes from Schoenage, who used it in a numerical context. Should I
put the reference to
Schoenage's paper, or is it sufficient to write "See [BFSS] and references
within." ?
