• Avoid maps:

  6) Try replace Edge * by indexes in Neigbours and elements (anyway we have mesh pointer in elements so it is accessible also from Neigbours)

TODO:

• use std::is_any for setting is_neigbour
• possibly make appropriate constructors for Edge and Neighbour
• check side!=-1 when searching neigbouring element
• process boundary elements first, there should be no Neigh, but check it set Edge and boundary there
