Description: Implements the Changes-in-Changes (CIC) estimator of Athey and
    Imbens (2006) <doi:10.1111/j.1468-0262.2006.00668.x> combined with
    synthetic control methods. Provides both the continuous CIC estimator
    (Theorem 3.1) and the discrete CIC estimator (Theorem 4.1) for
    integer-valued outcomes, with analytic and bootstrap inference.
    Also provides nonparametric estimation of the entire counterfactual
    distribution of outcomes for a treated group, allowing evaluation of
    average, quantile, and distributional treatment effects. Synthetic
    control weights are constructed via elastic net regularization to
    handle settings with many potential control units.
