I am a fan of Gota, I hope Gota will become better

ADD Feature：

  1. Groupby
  2. Aggregation
groups := df.GroupBy("key1", "key2") // Group by column "key1", and column "key2" 
aggre := groups.Aggregation([]AggregationType{Aggregation_MAX, Aggregation_MIN}, []string{"values", "values2"}) // Maximum value in column "values",  Minimum value in column "values2"
