  4. **      Project:        #1 - Random Number Game
  5. **      Version:        1.3 More bug fixes...
  6. **      Disclaimer:
  7. **      My compiler did not like splitting System.out lines into multiple lines.
  8. **      Be it either because of Java 7 or 8, I do not know, but it would not
  9. **      compile if I split up the print statement.
  10. **
  11. **      Points are not influenced if the number is invalid, out of range, or part of a command.
