Description: Tools for blinded sample size re-estimation (BSSR) in two-arm clinical 
    trials with binary endpoints, together with the exact power and sample size 
    calculations that the re-estimation relies on. Five exact statistical tests are 
    implemented: Pearson chi-squared, Fisher exact, Fisher mid-p, Z-pooled exact 
    unconditional, and Boschloo exact unconditional. Each test is available with a 
    one-sided or a two-sided alternative, and the exact unconditional tests can be 
    combined with the Berger-Boos procedure. Sample sizes can be re-estimated either at 
    the planning stage, to study the operating characteristics of a design, or from the 
    blinded data of a trial that is under way. Statistical methods based on Mehrotra et 
    al. (2003) <doi:10.1111/1541-0420.00051>, Berger and Boos (1994) 
    <doi:10.1080/01621459.1994.10476836> and Kieser (2020) 
    <doi:10.1007/978-3-030-49528-2_21>.
