 input structure. n (int):
 index of site in Structure object for which motif type is to be determined. approach (str):
 type of neighbor-finding approach, where "min_dist" will use the MinimumDistanceNN class, "voronoi" the VoronoiNN class, "min_OKeeffe" the MinimumOKeeffe class, and "min_VIRE" the MinimumVIRENN class. delta (float):
 tolerance involved in neighbor finding. cutoff (float):
 (large) radius to find tentative neighbors. Returns: neighbor sites. """
