Save & Load ChebPoly

[weymouth]

I'm creating a set of ChebPoly objects as a surrogate for an expensive function in a package and I need a way to save and reload these functions. Does this functionality exist?

I haven't written any specific serialization/deserialization routines, but you can probably just use JLD2.jl?

Alternatively, the ChebPoly data structure is pretty simple, mainly just an array of coefs, so you an save those however you want:

FastChebInterp.jl/src/FastChebInterp.jl

Lines 37 to 41 in 35eb4f5

	struct ChebPoly{N,T,Td<:Real} <: Function
	coefs::Array{T,N} # chebyshev coefficients
	lb::SVector{N,Td} # lower/upper bounds
	ub::SVector{N,Td} # of the domain
	end

Yes, that works fine.
