get_covbeta

Compute cov(beta) as a Function of varpar of an LMM

At the optimum cov(beta) is available as vcov(lmer-model). This function computes cov(beta) at non (RE)ML estimates of varpar.

get_covbeta(varpar, devfun)

`varpar`	variance parameters; `varpar = c(theta, sigma)`.
`devfun`	deviance function as a function of theta only.

cov(beta) at supplied varpar values.
