Usage
>>> from ground.base import get_context
>>> context = get_context()
>>> Box, Point, Segment = context.box_cls, context.point_cls, context.segment_cls
>>> from locus import kd
>>> points = list(map(Point, range(-10, 11), range(0, 20)))
>>> kd_tree = kd.Tree(points)
>>> kd_tree.nearest_index(Point(0, 0)) == 5
True
>>> kd_tree.nearest_point(Point(0, 0)) == Point(-5, 5)
True
>>> kd_tree.n_nearest_indices(2, Point(0, 0)) == [6, 5]
True
>>> kd_tree.n_nearest_points(2, Point(0, 0)) == [Point(-4, 6), Point(-5, 5)]
True
>>> kd_tree.find_box_indices(Box(-1, 1, 0, 10)) == [9, 10]
True
>>> kd_tree.find_box_points(Box(-1, 1, 0, 10)) == [Point(-1, 9), Point(0, 10)]
True
>>> from locus import r
>>> boxes = list(map(Box, range(-10, 11), range(0, 20), range(-20, 0), range(-10, 11)))
>>> r_tree = r.Tree(boxes)
>>> r_tree.nearest_index(Point(0, 0)) == 10
True

Development
Bumping version
Preparation
Install
bump2version.
Pre-release
Choose which version number category to bump following semver
specification.
Test bumping version
bump2version --dry-run --verbose $CATEGORY

where $CATEGORY is the target version number category name, possible
values are patch/minor/major.
Bump version
bump2version --verbose $CATEGORY

This will set version to major.minor.patch-alpha.
Release
Test bumping version
bump2version --dry-run --verbose release

Bump version
bump2version --verbose release

This will set version to major.minor.patch.
Running tests
Install dependencies
python -m pip install -r requirements-tests.txt
