We do not have invented that wheel. It should not be too hard to
generalize what we do with Rcpp::Matrix
You can ignore the member functions that have diag in their names.
although, we would probably also have to extend the Vector::operator()
for more dimensions, and probably also Vector::offset.
I feel somewhat lazy here, but if you or someone else decides to pick it
up, I will have a look.
