Ways to initialize a NeighborLists object
	NeighborLists ()
	Constructor for the purpose of classes who have NeighborLists as a member object. More...

	NeighborLists (view_type cr_neighbor_lists, view_type number_of_neighbors_list, internal_row_offsets_view_type neighbor_lists_row_offsets, bool compute_max=true)
	Constructor for when compressed row `cr_neighbor_lists` is preallocated/populated, `number_of_neighbors_list` and `neighbor_lists_row_offsets` have already been populated. More...

	NeighborLists (view_type cr_neighbor_lists, view_type number_of_neighbors_list)
	Constructor for when compressed row `cr_neighbor_lists` is preallocated/populated, and `number_of_neighbors_list` is already populated, and row offsets still need to be computed. More...
