Usage of Halo and Stencil in dash #195

Hi,

for a student project, I am currently writing a stencil application. Can anybody tell me how to use dash::HaloBlock and stencils? There is some code and documentation in dash, however for me it is not clear how to create a HaloBlock from a dash::NArray.

From the meeting in Munich I thought this is supported by dash.

Halo Blocks would also be nice for the astro tutorial.

Let's have a Skype session on that. The actual missing part is automatic packing of boundary regions. We don't have it yet, but HaloBlock will simplify it a lot.

... oh, yes: the changes by @dhinf are not merged in development
