Description: Computes experimental designs for two-arm experiments with
    covariates using multiple methods, including: (0) complete randomization
    and randomization with forced-balance; (1) greedy optimization of a balance
    objective function via pairwise switching; (2) numerical optimization via
    'gurobi'; (3) rerandomization; (4) Karp's method for one covariate; (5)
    exhaustive enumeration for small sample sizes; (6) binary pair matching
    using 'nbpMatching'; (7) binary pair matching plus method (1) to further
    optimize balance; (8) binary pair matching plus method (3) to further
    optimize balance; (9) Hadamard designs; and (10) simultaneous multiple
    kernels. For the greedy, rerandomization, and related methods, three
    objective functions are supported: Mahalanobis distance, standardized sums
    of absolute differences, and kernel distances via the 'kernlab' library.
    This package is the result of a stream of research that can be found in
