The program quickly outputs n random integers in the range from a to b. The integers are drawn from a uniform distribution to make selection of integers equally probable.

This program is intended to be especially quick with very large ranges of integers and selecting only a very small number of those integers.

User specifies whether output is sorted or random order.

User specifies whether to remove duplicate integers or to allow duplicate integers.
