Explanation

The Game of Life

To run the provided tests, run composer test-gol.

Write some code that evolves generations through the [Conway's game of

life](https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life). The input will be a game board of cells, either alive (1) or dead

(0).

The code should take this board and create a new board for the

next generation based on the following rules:

1. Any live cell with fewer than two live neighbors dies (underpopulation)

2. Any live cell with two or three live neighbors lives on to

the next generation (survival)

3. Any live cell with more than three live neighbors dies

(overcrowding)

4. Any dead cell with exactly three live neighbors becomes a

live cell (reproduction)

As an example, this game board as input:

0 1 0 0 0

1 0 0 1 1

1 1 0 0 1

0 1 0 0 0

1 0 0 0 1

Will have a subsequent generation of:

0 0 0 0 0

1 0 1 1 1

1 1 1 1 1

0 1 0 0 0

0 0 0 0 0
