Write a Java program to compute all data cuboids for the facts count and avg_income,
where avg_income represents the average income for a cell. The program should take a command
line parameter n representing the dimension of the cuboid and print out the corresponding cuboids.
DataCube 0 will print out the apex cuboid
DataCube n will print out all level n cuboids (n <= 3 in this case)
Either print the cuboids for both count and avg_income or use that as another command line parameter.
