ColumnStatsGrouping | @glysade/publisher

ColumnStatsGrouping defines the grouping parameters used to group column statistics by the data in another column. This can group both numeric and categorical columns. If the grouping column is numeric it is possible to define the min, max and number of bins for the grouping. If the grouping column is categorical the data is simply grouped by value.
