BootCI                  Enter first level estimates and second level
                        estimates, get bootstrap interval, from the
                        pivotal bootstrap t (Efron and Tibshirani 1994,
                        also endorsed by Hesterberg 2015).
BootGlmm                computes bootstrap resamples of your data,
                        stores estimates + SEs.
CombineResampledLists   When running BootGlmm in distributed fashion,
                        combines output
GetRand                 this takes in a formula with bars and gives
                        back the plain names of the columns
test_data               Simulated data containing three fixed effects
                        and one random effect
