Added command-line arguments (in the order width, height, seed, death limit, birth limit) and defaults

 # Simple procedural generation of "dungeon maps"
 
-Basic proof of concept. No real refinement at this point.
+Basic proof of concept for a "cellular automata" model. No real refinement at this point.
 
 Initial work based on [this tutorial](https://gamedevelopment.tutsplus.com/tutorials/generate-random-cave-levels-using-cellular-automata--gamedev-9664).
