This replaces read_neighbours() in order to avoid using NGH preprocessor.
TODO:
Avoid maps:
4) replace EdgeVector by std::vector<Edge> (need not to know the size)
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 bc_elements first, there should be no Neigh, but check it set Edge and boundary there
