gmsh example

[scdivi]

Dear developers,

Nutils supports gmsh-generated mesh by importing the .msh file using mesh.gmsh(filename.msh). However, there is no good gmsh-based example (with definition of boundary tags and direction of point definition). It would be great to add key points to note in documentation or create a good example.

Best,
Sai.

I made a gmsh example here: https://github.com/scdivi/nutils-gmsh. It has clear instructions to create a .geo file with boundary tags and reading it in nutils.
