In some cases like symmetric with CRS Scheme The cells indicated with numbers has a non straigh-forward neighborhood. This function calculate the list of the domain cells with normal symmetric neighborhood type and compute a list of cells with more complex neighboring cells.

Parameters

sub_keys	array that contain the position of the sub-sub-domains indicated with numbers in grid coordinates + for each its neighboring cells
dom_cells	list of all the domain cells
dom_subsub	cells with normal neighborhood
loc_box	array of local sub-sub-domain in grid coordinates
proc_box	Processor bounding box in local coordinates
