[Dune] Dune dual mesh

[Bartosz]

Hello,

My name is Bartosz Bartmanski and I am a PhD student at University of 
Oxford.

I'm working on stochastic simulations of reaction-diffusion systems and 
I'm trying to use Dune to get a discretisation of the Laplacian operator 
for any given mesh. However, my simulations require the Laplacian to be 
derived from the centers of the given mesh and so I was wondering there 
is a way to process a given Gmsh generated mesh to a dual mesh.

Thank you for any help!

Best regards,

Bartosz Bartmanski
