Description: Provide estimation and data generation tools for new multivariate frailty models.
             This version includes the gamma, inverse Gaussian, weighted Lindley, Birnbaum-Saunders,
	     truncated normal, mixture of inverse Gaussian, mixture of Birnbaum-Saunders, 
             generalized exponential and Jorgensen-Seshadri-Whitmore as the distribution for
             frailty terms. For the basal model, it is considered a parametric approach based 
             on the exponential, Weibull and the piecewise exponential distributions as well as a 
             semiparametric approach. For details, see Gallardo et al. (2024) <doi:10.1007/s11222-024-10458-w>,
