Polynomial interpolation

[konsumlamm]

Is polynomial interpoaltion in scope for this library? I thought about adding Lagrange and Hermite interpolation. The types could be

lagrange :: (G.Vector v a, Eq a, Fractional a) => [(a, a)] -> Poly v a

hermite :: (G.Vector v a, Eq a, Fractional a) => [(a, [a])] -> Poly v a

It makes sense to me, yes.
