"""Nearest Neighbor Detection for Bioconductor Packages.
Implements exact and approximate methods for nearest neighbor detection,
in a framework that allows them to be easily switched within
Bioconductor packages or workflows. Exact searches can be performed
using the k-means for k-nearest neighbors algorithm or with vantage
point trees. Approximate searches can be performed using the Annoy or
HNSW libraries. Searching on either Euclidean or Manhattan distances is
supported. Parallelization is achieved for all methods by using
BiocParallel. Functions are also provided to search for all neighbors
within a given distance."""
