 ## Usage
-The 'sample_admb' function draws posterior samples from an ADMB model using
-an MCMC algorithm (NUTS by default). The returned fitted object contains
-samples and other information. The function 'extract_samples' can be used
-to get posterior samples (post warmup and thinning) into a data frame for
-inference, while 'launch_shinyadmb' can be used for interactive diagnostics
