Working with xtensor

The xtensor library and surrounding ecosystem provides a quite powerful way of working with N-D arrays in C++ and plays nicely with standard C++ containers. Of course C remains the lingua franca in the programming world both for library interfaces and for working on a wide range of systems. It would be interesting to explore in what ways xnd can interoperate with xtensor.

This appears to be better suited at xnd. Migrating the issue over there. Sorry for the noise.

Apart from integration with standard C++ containers, I think a lot of work has been put into making xtensor fast. Especially, gumath kernels could benefit from SIMD support and lazy evaluation.
