My implementation of Conway's Game of Life in C# using test-driven development.
- Any live cell with fewer than two live neighbours dies (referred to as underpopulation or exposure).
- Any live cell with more than three live neighbours dies (referred to as overpopulation or overcrowding).
- Any live cell with two or three live neighbours lives, unchanged, to the next generation.
- Any dead cell with exactly three live neighbours will come to life.
