GroupBy - single array of groupby columns indices
Browse files Browse the repository at this point in the history 
Rework GroupBy functionality to work with single array of groupby
columns indices. This also fixes previous issue with ordering
of groupby columns in the output frame and allows it to be used through
Ast api. Use BufferedStrings internally to achieve better memory
efficiency.
