    Description
     
    A tree of t-digest centroids.
     
    A single centroid which represents a number of data points.
    Maintains histogram buckets that are constant width in base-2 floating point representation space.
    Abstract class that describes how a Histogram should work.
    An AVL-tree structure stored in parallel arrays.
    A stack of int values.
     
    Maintains a t-digest by collecting new points in a buffer that is then sorted occasionally and merged into a sorted array that contains previously computed centroids.
     
    Very simple variable byte encoding that always uses 64bit units.
    Static sorting methods
    Adaptive histogram based on something like streaming k-means crossed with Q-digest.
