TODO:

  • Avoid maps:

    5) need not to have temporary array for Edges, only postpone setting pointers in elements and set them after edges are found; we can temporary save Edge index instead of pointer in Neigbours and elements

    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
