Description: Implements methods developed by Ding, Feller, and Miratrix
        (2016) <doi:10.1111/rssb.12124> <doi:10.48550/arXiv.1412.5000>,
        and Ding, Feller, and Miratrix (2018)
        <doi:10.1080/01621459.2017.1407322>
        <doi:10.48550/arXiv.1605.06566> for testing whether there is
        unexplained variation in treatment effects across observations,
        and for characterizing the extent of the explained and
        unexplained variation in treatment effects. The package
        includes wrapper functions implementing the proposed methods,
        as well as helper functions for analyzing and visualizing the
        results of the test.
