 *
+* This code is structured in a scalable and introspective way:
+* 	- Snake object is reusable as a prototype enabling multiple games
+* 		to run at the same time
+* 	- Snake implements an open external control scheme, i.e. it does not 
+* 		impose a specific way to implementing the way to control the game
+* 	- Simple (but not trivial) code and code structure
+* 	- Introspective: no hidden/masked state or functionality
+* 	- No external dependencies
+*
+*
+* Goals:
+* 	- Show that the "intuitive" is not the only approach
+* 	- Show that the "intuitive" is not allways the simplest
+* 	- Show one approach to a scalable yet simple architecture
