[Dune] Multilinear interpolation in Dune?

[Atgeirr Rasmussen]

Dear Dune!

We have a need for multilinear interpolation (5d), and I thought perhaps it already exists in Dune,
however I could not find any such feature (I looked briefly in dune-common). If this exists already
we would prefer to use it, otherwise we are considering the following library:

http://rncarpio.github.io/linterp/

So have I missed something, perhaps in a different module than dune-common?

Yours,
