It is\npart of the 'TDAverse' suite of packages, which is designed to\nprovide a collection of packages for enabling machine learning\nand data science tasks using persistent homology. Implements a\nclass for hosting persistence data, a number of coercers from\nand to already existing and used data structures from other\npackages and functions to compute distances between persistence\ndiagrams. A formal definition and study of bottleneck and\nWasserstein distances can be found in Bubenik, Scott and\nStanley (2023) .
