Description: Modeling periodic mortality (or other time-to event)
        processes from right-censored data. Given observations of a
        process with a known period (e.g. 365 days, 24 hours),
        functions determine the number, intensity, timing, and duration
        of peaks of periods of elevated hazard within a period.  The
        underlying model is a mixed wrapped Cauchy function fitted
        using maximum likelihoods (details in Gurarie et al. (2020)
        <doi:10.1111/2041-210X.13305>). The development of these tools
        was motivated by the strongly seasonal mortality patterns
        observed in many wild animal populations. Thus, the respective
        periods of higher mortality can be identified as "mortality
        seasons".
