/* Write an animation that lets the computer play the game of ``Life.''
The game goes as follows: the user specifies the size of game board,
a matrix, and also gives the starting positions of where some pebbles(``cells'') live.
Every second, the computer updates the board, creating and removing cells,
according to the following rules:
    - an empty board position that is surrounded by exactly three cells gets
      a cell placed on it. (The new cell ``comes to life.'')
    - a board position occupied by a cell retains the cell if the position was surrounded
      by exactly 2 other cells. (Otherwise the cell disappears---``dies''---due to
     ``loneliness'' or ``overcrowding.'')
Here is an example of two seconds of the animation on a 5-by-5 board, where an X denotes a cell and . denotes an empty space:
.X.XX     ...XX     ...XX
X...X     ....X     ....X
XXX..  => X.X..  => ...X.
..X.X     X.X..     ..XX.
X...X     ...X.     .....
