+/* Conway's Game of Life
+ * https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life
+ *
+ * The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells,
+ * each of which is in one of two possible states, alive or dead.
+ *
+ * Every cell interacts with its eight neighbours, which are the cells that are horizontally, vertically,
+ * or diagonally adjacent.
+ *
+ * At each step in time, the following transitions occur:
+ *   1. Any live cell with fewer than two live neighbours dies, as if caused by under-population.
+ *   2. Any live cell with two or three live neighbours lives on to the next generation.
+ *   3. Any live cell with more than three live neighbours dies, as if by over-population.
+ *   4. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.
