Description of Primes and Twin Primes: List and Count

This application lists primes and pairs of twin primes within a given range.
The program offers to enter an initial number and choose an interval from three alternatives (10, 100, 1000). There is also an additional option for entering both initial and terminal numbers. In this latter case, allowed maximum and minimum differences of the initial and the terminal numbers are correspondingly 2000 and 2.
Besides getting the expected list of primes and pairs of twin primes, forward and backward navigation is also possible. The application also presents a count of primes and pairs of twin primes within the range.
