Remove elements with dimension not equal to dim
from element_list
. Index of the first element of dimension dim-1
, is returned in element_idx
. If no such element is found the method returns false, if one such element is found the method returns true, if more elements are found we report an user input error.

This replaces read_neighbours() in order to avoid using NGH preprocessor.
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)
