Conway's Game of Life

Evolution Rules

Birth: Any dead cell with exactly three live neighbours becomes a live cell.
Survival: Any live cell with two or three live neighbours lives in the next generation.
Death by loneliness: Any live cell with fewer than two live neighbours dies, as in under-population.
Death by overcrowding: Any live cell with more than three live neighbours dies, as in over-population.

Particle placement (Q, W, E, R): Particles are placed (key Q, W, E, R) into the simulation area based on the center of the particle using direction keys (right, left, up, down).
Particle rotation (1, 2, 4): Key 1, 2, 4 can be used to rotate a specific particle (particle Q, W, R) 90 degrees in clockwise direction.
Cell deletion (3): Key 3 is used to delete a single cell where cursor is on.
Clear screen (0): Key 0 is used to clear simulation area.
Generate new random particle (T): User can generate new particle-R using key T.
Generate new random particle and place randomly (Y): User can generate new particle-R and place randomly by using key Y.
Generate next step (space): When user presses space key, the next iteration of the simulation is calculated and printed.
