At this point, the neighbourhood construction is working fine. I have now to construct it in a periodic case.

At this point, I have an issue on Choleski with 32 ranks on advection-2d --min-level 4 or lower (the modified balanced case). Here is the error :

terminate called after throwing an instance of 'std::out_of_range'
  what():  FIELD ERROR on level 7: try to find interval [30, 31[@0:1

This is because one cell is coarser than its subdomain. I don't think it is related to this PR anyway ...
