In order to handle both variables equivalently
we maintain a list of coefficients for terms of the same total degree.
That is
eval [[a], [b,c], [d,e,f]] (x,y) ==
a + b*x+c*y + d*x^2+e*x*y+f*y^2
Although the sub-lists are always finite and thus are more like polynomials than power series,
division and square root computation are easier to implement for power series.

Since the inner series must start with a zero,
the first term is omitted in y.
