ras.Randomizer creates multiple series of groups each
with randomly sampled observations. Observations are distributed such as
that there are no repeated entries between groups/within a series.
Number of groups in a series is calculated as
length(master_list) divided by group_size,
rounded up to nearest integer. If an observation can not be found (for
example because the groups can not be filled evenly) an error message is
printed to the console and N/A inserted instead.
