Kdtrees

-  : [`_utils.format_array`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_utils.py) is now removed and all code is changed to reflect. **This is a major feature. `kdtrees 0.1.7` is not backwards-compatible.**
-  : `__len__` no longer a required function in [`KDTreeType`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtree_type.py) as per [ISS 9](https://github.com/paradoxysm/kdtrees/issues/9).
-  : [`_kdtrees.initialize`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtrees.py) now correctly handles `accept` overrides to update presorted arrays.
-  : [`_utils.check_dimensionality`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_utils.py) now properly checks `accept` overridden types without unexepected errors.
-  : [`KDTreeType`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtree_type.py) now implements `__lt__` for proper sorting.
-  : [`KDTreeType`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtree_type.py) no longer extends `list` so that it can be properly wrapped into a list.
-  : [`_kdtrees.nearest_neighbor`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtrees.py) and [`_kdtrees.proximal_neighbor`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_kdtrees.py) now properly call [`_utils.distance`](https://github.com/paradoxysm/kdtrees/blob/0.1.7/kdtrees/_utils.py) with `accept` override applied as per [ISS 7](https://github.com/paradoxysm/kdtrees/issues/7).
-  : Updated documentation to reflect changes.
-  : Implemented a number of new tests in [`tests`](https://github.com/paradoxysm/kdtrees/tree/0.1.7/tests/)

-  : `__iter__` no longer required for [`KDTreeType`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtree_type.py) as per [ISS 2](https://github.com/paradoxysm/kdtrees/issues/2).
-  : `height` no longer an attribute in [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtree.py) as per [ISS 6](https://github.com/paradoxysm/kdtrees/issues/6).
-  : [`setup.py`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/setup.py) fixed with updates to metadata.
-  : Fixed equality and comparison checks in [`_kdtrees.insert`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtrees.py), [`_kdtrees.search`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtrees.py), and [`_kdtrees.delete`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtrees.py) as per [ISS 3](https://github.com/paradoxysm/kdtrees/issues/3).
-  : [`_utils.distance`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_utils.py) now implemented as per [ISS 4](https://github.com/paradoxysm/kdtrees/issues/4). Allows accept overriding to properly use `nearest_neighbor` and `proximal_neighbor`.
-  : Accept overriding is now properly implemented without fatal errors. This affected [`_utils.format_array`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_utils.py) and [`_utils.check_dimensionality`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_utils.py) as per [ISS 5](https://github.com/paradoxysm/kdtrees/issues/5).
-  : Fixed mask extractions on presorted arrays in [`_kdtrees._initialize_recursive`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtrees.py).
-  : [Overview](https://github.com/paradoxysm/kdtrees/blob/0.1.6/README.mdOverview) description of [README](https://github.com/paradoxysm/kdtrees/blob/0.1.6/README.md) is now expanded slightly and includes a link to [Wikipedia](https://en.wikipedia.org/wiki/K-d_tree) for further reading.
-  : Updates to [doc_kdtree.md](https://github.com/paradoxysm/kdtrees/blob/0.1.6/doc/pydoc/doc_kdtree.md) to fix the [`initialize`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/doc/pydoc/doc_kdtree.mdinitialize) header.
-  : Added documentation for [`KDTreeType`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/doc/pydoc/doc_kdtree_type.md).
-  : Created a variety of issues and pull request templates.
-  : Addition of CodeClimate and FOSSAS license scanning.
-  : `KDTreeType` is now in [`kdtrees._kdtree_type`](https://github.com/paradoxysm/kdtrees/blob/0.1.6/kdtrees/_kdtree_type.py)

-  : [`kdtrees`](https://github.com/paradoxysm/kdtrees/tree/0.1.5) is now implemented. We're live!
-  : [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_kdtree.py) can now be modified by insertion and deletion.
-  : [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_kdtree.py) now maintains itself as a pseudo-balanced tree.
-  : [`kdtrees._utils`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_utils.py) now implements `format_array` and `check_dimensionality`.
-  : [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_kdtree.py) now supports k-nearest neighbors through `nearest_neighbor`.
-  : [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_kdtree.py) now supports finding neighbors within a specified distance through `proximal_neighbor`.
-  : [`KDTree`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/_kdtree.py) now supports custom types through the use of an `accept` clause. See [`kdtrees.kdtree_type`](https://github.com/paradoxysm/kdtrees/blob/0.1.5/kdtrees/kdtree_type.py) for implementation of required abstract base superclass.
-  : Updates made to the [README](https://github.com/paradoxysm/kdtrees/blob/0.1.5/README.md) and [CHANGES](https://github.com/paradoxysm/kdtrees/blob/0.1.5/CHANGES.md).
-  : [Documentation](https://github.com/paradoxysm/kdtrees/tree/0.1.5/doc) initialized and [pydoc](https://github.com/paradoxysm/kdtrees/tree/0.1.5/doc/pydoc) created.
