Detailed Description

The grouped data corresponding to a groupby operation on a set of values.

A groups object holds two tables of identical number of rows: a table of grouped keys and a table of grouped values. In addition, it holds a vector of integer offsets into the rows of the tables, such that offsets[i+1] - offsets[i] gives the size of group i.
