Description: Implements hierarchically regularized entropy balancing
        proposed by Xu and Yang (2022) <doi:10.1017/pan.2022.12>. The
        method adjusts the covariate distributions of the control group
        to match those of the treatment group. 'hbal' automatically
        expands the covariate space to include higher order terms and
        uses cross-validation to select variable penalties for the
        balancing conditions.
