 Command line usage for hashed based GroupBy:
 ```
 make groupby_hash
 ./groupby_hash                                                           # Data Entries:  100k, key_columns: 2, row_columns: 3, unique keys per column: 4

 The program will populate random data, compute on CPU and GPU then validate the results.
