Description: Provides a number of utility functions useful for
        manipulating large histograms.  This includes methods to trim,
        subset, merge buckets, merge histograms, convert to CDF, and
        calculate information loss due to binning.  It also provides a
        protocol buffer representation of R's native histogram class to
        allow histograms over large data sets to be computed and
        combined in distributed analytical pipelines.  Implements
        bin-by-bin histogram distance measures described in Rubner,
        Tomasi and Guibas (2000) <doi:10.1023/A:1026543900054>, Swain
        and Ballard (1991) <doi:10.1007/BF00130487>, and Puzicha,
        Hofmann and Buhmann (1997) <doi:10.1109/CVPR.1997.609331>, and
        average shifted histograms as in Scott (2015,
        ISBN:9781118575536).
