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 not 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.
