IndexError in Network.calc_net_stats() --> dict for node2coords?

[jGaboardi]

Probably should convert all lookups to dictionaries from lists. Not sure why I made all these lists in dissertation implementation...

See also #29

To reproduce:

bbox = (-84.279,30.480,-84.245,30.505)
f = "zip://test_data/Edges_Leon_FL_2010.zip!Edges_Leon_FL_2010.shp"
gdf = geopandas.read_file(f, bbox=bbox)
gdf = gdf.to_crs("epsg:2779")
yes_roads = gdf["MTFCC"].str.startswith("S")
roads = gdf[yes_roads].copy()

kwargs = {"s_data": roads.copy(), "from_raw": True}
attr_kws = {"attr1": ATTR1, "attr2": ATTR2}
kwargs.update(attr_kws)
comp_kws = {"record_components": True, "largest_component":True}
kwargs.update(comp_kws)
graph_elems_kws = {"def_graph_elems": True}
kwargs.update(graph_elems_kws)
geom_kws = {"record_geom": True, "calc_len": True}
kwargs.update(geom_kws)
mtfcc_kws = {"discard_segs": discard_segs, "skip_restr": SKIP_RESTR}
mtfcc_kws.update({"mtfcc_split": INTRST, "mtfcc_intrst": INTRST})
mtfcc_kws.update({"mtfcc_split_grp": SPLIT_GRP, "mtfcc_ramp": RAMP})
mtfcc_kws.update({"mtfcc_split_by": SPLIT_BY, "mtfcc_serv": SERV_DR})
kwargs.update(mtfcc_kws)
net = tigernet.Network(**kwargs)
net.calc_net_stats()
