Description: Maximum likelihood estimation of copula-based zero-inflated 
    (and non-inflated) Poisson and negative binomial count models, based on the 
    article <doi:10.18637/jss.v109.i01>. Supports Frank and Gaussian copulas. 
    Allows for mixed margins (e.g., one margin Poisson, the other zero-inflated 
    negative binomial), and several marginal link functions. Built-in methods for 
    publication-quality tables using 'texreg', post-estimation diagnostics using 
    'DHARMa', and testing for marginal zero-modification via <doi:10.1177/0962280217749991>.
