abstract: 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 inference, maximum likelihood, and AIC, BIC,
  and RMSE for goodness-of-fit.
