Description: Provides some basic routines for simulating a clinical
        trial. The primary intent is to provide some tools to generate
        trial simulations for trials with time to event outcomes.
        Piecewise exponential failure rates and piecewise constant
        enrollment rates are the underlying mechanism used to simulate
        a broad range of scenarios such as those presented in Lin et
        al. (2020) <doi:10.1080/19466315.2019.1697738>. However, the
        basic generation of data is done using pipes to allow maximum
        flexibility for users to meet different needs.
