Returns the calculated variance-covariance matrix for a `mcml` object. The generating Model object has several methods to calculate the variance-convaariance matrix. For the standard GLS information matrix see `Model$information_matrix()`. Small sample corrections can be accessed directly from the generating Model using `Model$small_sample_correction()`. The varaince-covariance matrix including the random effects can be accessed using `Model$information_matrix(include.re = TRUE)`.
