[Dune] element aggregation

[arya fallahi]

Dear Dune team,

In my project, I need to aggregate about ten elements of a grid and treat this new element as an Entity containing all the edges and faces of the basic elements. Before, I start doing this, I would like to know if there is any class already defined within the dune project that does this task. I will be thankful if you let me know about this matter.

Thanks and best regards,
