Description: A fast reimplementation of several density-based
        algorithms of the DBSCAN family. Includes the clustering
        algorithms DBSCAN (density-based spatial clustering of
        applications with noise) and HDBSCAN (hierarchical DBSCAN), the
        ordering algorithm OPTICS (ordering points to identify the
        clustering structure), shared nearest neighbor clustering, and
        the outlier detection algorithms LOF (local outlier factor) and
        GLOSH (global-local outlier score from hierarchies). The
        implementations use the kd-tree data structure (from library
        ANN) for faster k-nearest neighbor search. An R interface to
        fast kNN and fixed-radius NN search is also provided.  Hahsler,
