Prime Number Generator
This program accepts any positive integer greater than 3. If the number is a
prime number (not evenly divisible by integers other than itself and 1), then
the program returns the input value. If the input is not a prime number, then
the program returns the first prime number larger than the input.
The program identifies non–prime numbers by exhaustively trying all possible
factors. If a number is riot prime, the program adds 2 (assuring that the value
is still odd) and tests to see if it, has found a prime. This process continues until
a prime number is found.
