Description: Implements the double-sampling bounds estimator of Coppock,
    Gerber, Green, and Kern (2017) <doi:10.1017/pan.2016.6> for randomized
    experiments with nonignorable missing outcomes. Provides worst-case
    (Manski) bounds, double-sampling bounds with analytic variance and
    Imbens-Manski confidence intervals, Lee (2009) <doi:10.1111/j.1467-937X.2009.00536.x> trimming
    bounds with analytic and bootstrap standard errors, covariate
    adjustment via poststratification, and a sensitivity analysis for
    violations of the outcome stability assumption.
