Description: Implements a general framework for globally optimizing
        user-specified objective functionals over interpretable binary
        weight functions represented as sparse decision trees, called
        ROOT (Rashomon Set of Optimal Trees). It searches over
        candidate trees to construct a Rashomon set of near-optimal
        solutions and derives a summary tree highlighting stable
        patterns in the optimized weights. ROOT includes a built-in
        generalizability mode for identifying subgroups in trial
        settings for transportability analyses (Parikh et al. (2025)
        <doi:10.1080/01621459.2025.2495319>).
