/**
 * Sine Wave
 *
 * Based on the Sine Wave program here
 * https://github.com/coding-horror/basic-computer-games/blob/main/78%20Sine%20Wave/sinewave.bas
 *
 * Note:  The idea was to create a version of the 1970's Basic program in Java, without introducing
 *        new features - no additional text, error checking, etc has been added.
