About RTree Data Structure Persistent Storage

[RuoCJ]

I wanted to persist the built Rtree in my code, but what was stored was an empty pickle file. The code is as follows:

import rtree
import pandas as pd
import pickle
spatial_index = rtree.index.Index()

df = pd.read_csv("block_loc", sep='\t')

for i, row in df.iterrows():
	id = int(row[0])
	longitude = float(row[1])
	latitude = float(row[2])
	print(id, longitude, latitude)
	spatial_index.insert(id, (longitude, latitude))
print(spatial_index)
with open("spatial_index.pickle", "wb") as f:
	pickle.dump(spatial_index, f)

Rtree object：rtree.index.Index(bounds=[-150, 38, 150, 40], size=689274)

Objects read from pickle file：rtree.index.Index(bounds=[1.7976931348623157e+308, 1.7976931348623157e+308, -1.7976931348623157e+308, -1.7976931348623157e+308], size=0)

Why is this

See #87, pickling is currently broken, fixes would be very appreciated.

Excuse me, do you want me to try fixing this bug？

If you can that would be great. I tried in #197 but couldn't come up with a satisfying solution.
