=========

A [vantage-point tree][vp-tree] implementation backed by a vector for good performance with **zero** lines of `unsafe`

code.

Provides bulk insert/removal operations (to maintain balance without too much extra bookkeeping), 

and the [*k*-Nearest Neighbors (k-NN)][knn] algorithm.

Multiple distance functions are provided by default, including Hamming and Levenshtein distance functions for strings.
