Description Author

This class can check whether a number is prime.

It first checks if the number is divisible by small prime integers.

If it passes the low prime numbers check, the class checks if the number ends with a digit that all higher prime numbers end.

On the final step it checks if the number is divisible by any of the prime numbers that are found incrementally.
