/*
* conways_game_of_life.mj -- Plays Conway's Game of Life.
*
* This is a simulator for Conway's Game of Life [1]. To get the maximum fun
* out of it, you need a video terminal that understands ANSI escape sequences.
* Then, piping the output of this program through a filter as explained in
* `hello_world.mj` will show you a fancy animation of the game. If you cannot
* get access to a terminal (emulator) that is capable of this, you can set the
* variable `HAVE_ANSI` near the beginning of `main` to `false`. Then, the
* output will not use ANSI escape codes but look rather sad. You'll probably
* also want to reduce the iteration count in this case. Here are all
* variables that you might want to tweak.
*
* - `HAVE_ANSI` -- whether ANSI escape codes are supported by the terminal
* - `LINES` -- number of lines available on the terminal
* - `COLUMNS` -- number of columns available on the terminal
* - `ITERATIONS` -- number of iterations to play
* - `RANDOM_SEED` -- random seed for initializing the game
*
* Since MiniJava has no way to suspend, this program deliberately uses an
* inefficient strategy to print the output (knowing that terminals are
* *really* slow at interpreting ANSI escape codes). This means that the
* program will eat all your CPU while it is running. The update rate is about
* alright on my PC but if your computer is much faster or much slower, you
* might not enjoy the animation very much.
*
