Description
Extracting a square root of a power series is implemented in power_series_ring_element.pyx
. Could we have the more general "improving a root of a polynomial" Newton's method?
My use case is calculating Puiseaux expansions around points of algebraic curves.

Here's a stand-alone implementation that needs to be plugged into the hell that is
polynomial.roots()
.
