Description: Functions to design and apply tests that are anytime
        valid. The functions can be used to design hypothesis tests in
        the prospective/randomised control trial setting or in the
        observational/retrospective setting. The resulting tests remain
        valid under both optional stopping and optional continuation.
        The current version includes safe t-tests and safe tests of two
        proportions. For details on the theory of safe tests, see Ly,
        A, Boehm, Grunwald, Ramdas and van Ravenzwaaij (2024). "Safe
        Anytime-Valid Inference: Practical maximally flexible sampling
        designs for experiments based on e-values"
        (<doi:10.31234/osf.io/h5vae>) and Grunwald, de Heide and Koolen
        (2024) "Safe Testing" (<doi:10.1093/jrsssb/qkae011>), for
        details on safe logrank tests see ter Schure, Perez-Ortiz, Ly
        and Grunwald (2024) "The Anytime-Valid Logrank Test: Error
        Control under Continuous Monitoring with Unlimited Horizon"

        that allow for optional stopping"

        contingency table tests.
