/**
* Game of Orbit
* <p>
* Based on the BASIC game of Orbit here
* https://github.com/coding-horror/basic-computer-games/blob/main/68%20Orbit/orbit.bas
* <p>
* Note: The idea was to create a version of the 1970's BASIC game in Java, without introducing
* new features - no additional text, error checking, etc has been added.

* Converted from BASIC to Java by Darren Cardenas.
