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: https://github.com/JuliaMath/FastChebInterp.jl/blob/35eb4f518b5706d4d07e462c09dbcb15e880cfe2/src/FastChebInterp.jl#L37-L41

Yes, that works fine.
