Description: Functions to design and simulate optimal two-stage
        randomized controlled trials (RCTs) with ordered categorical
        outcomes, using rank-based tests and interim decision rules for
        futility and superiority, following Park (2025)
        <doi:10.1371/journal.pone.0318211>. The functions 'rule()',
        'op()' and 'design_table()' provide a single entry point for
        constructing designs, evaluating their operating
        characteristics, and tabulating several designs at once. The
        separate functions provided for each combination of test
        statistic and stopping rule up to version 1.0.2 were deprecated
        in 1.0.3 and are removed here. Please see the package reference
        manual and the vignette for details.
