Exact searches can be performed using the k-means for k-nearest neighbors algorithm, vantage point trees, or an exhaustive search. Approximate searches can be performed using the Annoy or HNSW libraries. Each search can be performed with a variety of different distance metrics, parallelization, and variable numbers of neighbors. Range-based searches (to find all neighbors within a certain distance) are also supported.

Implements the BumpyMatrix class and several subclasses for holding non-scalar objects in each entry of the matrix.
