A solution to Rails Conf 2018 live pairing.

Rules

• Any live cell with fewer than two live neighbors dies, as if by under population.
• Any live cell with two or three live neighbors lives on to the next generation.
• Any live cell with more than three live neighbors dies, as if by overpopulation.
• Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.
