Description: A low-level package for hosting persistence data. It is
        part of the 'TDAverse' suite of packages, which is designed to
        provide a collection of packages for enabling machine learning
        and data science tasks using persistent homology. Implements a
        class for hosting persistence data, a number of coercers from
        and to already existing and used data structures from other
        packages and functions to compute distances between persistence
        diagrams. A formal definition and study of bottleneck and
        Wasserstein distances can be found in Bubenik, Scott and
        Stanley (2023) <doi:10.1007/s41468-022-00103-8>. Their
        implementation in 'phutil' relies on the 'C++' Hera library
        developed by Kerber, Morozov and Nigmetov (2017)
        <doi:10.1145/3064175>.
