#GAME OF LIFE
Yet another implementation of Conway's Game of Life. Initially built as a straightforward kata. As an exercise, I sought two obvious optimizations:
- Instead of counting neighbors, I cached the number of neighbors for each cell, and updated them as I changed the value of a given cell.
- Instead of updating every cell, I maintained a set of those cells having a changing neighbor, and only updated those cells.
These required some changes to the initial design. Spiked a .LIF file reader and rewrote the mainline to read from STDIN. (If "RANDOM" is sent, then a random screen will be built.)
