This is a port of https://github.com/mourner/flatbush

To test: python test.py

Example:

from flatbush import FlatBush
fb = FlatBush()
# add two boxes
fb.add(30, 4, 32, 5) # x1,y1,x2,y2
fb.add(10, 60, 11, 63)
fb.finish();

# query
results = fb.search(minx, miny, maxx, maxy);
# results are an array of indices. The index starts at zero,
# and is the order in which you inserted elements into the tree.
