A factor with at most
maximum_levels, or a data.frame where each factor matches that requirement
Methods (by class)
factor: Group infrequent levels in a factor. Takes a factor, and if that factor has more than 'maximum_levels', it makes a table of level frequencies. The top (maximum_levels-1) are left unchanged, all less frequent levels are grouped into the level "other".
data.frame: Takes a data.frame, and applies group_levels.factor to each column
list: Takes a list of data.frames and applies
