/**
* Game of Bombardment
*
* <p>
* Based on the Basic game of Bombardment here
* https://github.com/coding-horror/basic-computer-games/blob/main/11%20Bombardment/bombardment.bas
*
* Note: The idea was to create a version of this 1970's Basic game in Java, without introducing
* new features - no additional text, error checking, etc has been added.
