Game of Life

Description
An implementation of Conway's Game of Life for the TRS-80 CoCo.
The player implements the starting pattern by drawing it on the screen using the keyboard.
- Any live cell with fewer than 2 or more than 3 live neighbors dies.
- Any live cell with two or three live neighbors lives on to the next generation.
- Any dead cell with exactly three live neighbors becomes a live cell through reproduction.
The player can advance by single steps, or set the game to automatically advance through multiple generations.
