Description: 
    Calibrates Bayesian two-stage designs for single-arm phase II trials with
    time-to-event endpoints using a window-cohort with controlled roll-on.
    Interim monitoring is anchored to a locked interim cohort and a
    pre-specified follow-up requirement, so analysis timing remains
    predictable while preserving follow-up maturity. The package searches
    feasible interim rules, optimizes final sample size and decision
    thresholds, evaluates operating characteristics by Monte Carlo simulation,
    and supports exponential, Weibull, log-normal, log-logistic, and
    user-defined baseline survival models. Related published foundations

    Whitehead (2015) <doi:10.1002/sim.6426>.
