While doing the simulations, I realize the degopt coefficients are created inside functions which also just return the graph. Sometimes I want to get the degopt coefficients (of say PS), modify them and then create a graph (e.g. to implement squaring in degopt coeffs).

Proposed solution: a function which extracts the degopt coefficients from a graph which was created with gen_degopt_poly.

(x,z)=get_degopt_coeffs(graph,k)

Returns x::Vector{Vector{Tuple{T,T}}} where C=eltype(graph) and y::Vector{T}.

I don't see any other simple solution than hardcoding the coefficient names.
