Description: Extensive functions for bivariate copula (bicopula)
        computations and related operations for bicopula theory. The
        lower, upper, product, and select other bicopula are
        implemented along with operations including the diagonal,
        survival copula, dual of a copula, co-copula, and numerical
        bicopula density. Level sets, horizontal and vertical sections
        are supported. Numerical derivatives and inverses of a bicopula
        are provided through which simulation is implemented. Bicopula
        composition, convex combination, asymmetry extension, and
        products also are provided. Support extends to the Kendall
        Function as well as the Lmoments thereof. Kendall Tau, Spearman
        Rho and Footrule, Gini Gamma, Blomqvist Beta, Hoeffding Phi,
        Schweizer- Wolff Sigma, tail dependency, tail order, skewness,
        and bivariate Lmoments are implemented, and positive/negative
        quadrant dependency, left (right) increasing (decreasing) are
        available. Other features include Kullback-Leibler Divergence,
        Vuong Procedure, spectral measure, and Lcomoments for fit and
        inference, Lcomoment ratio diagrams, maximum likelihood, and
        AIC, BIC, and RMSE for goodness-of-fit.
