+/**********************************************************************
+* 
+* Simple Snake 
+*
+* This code is designed to illustrate the non-intuitive approach to an
+* implementation, building a snake game as a cellular automaton rather
+* than the more intuitive, a set of entities (OOP) or a number of sets 
+* of procedures and data structures, directly emulating the "tactile" 
+* perception of the game, i.e. independent field, snakes, walls, apples
+* and their interactions.
+*
+* In this approach there are no entities, no snakes, no apples, no 
+* walls, just a set of cells in a field and cell behaviours per game 
+* step:
+* 	- empty cells, apples and walls just sit there
+* 	- "snake" cells:
+* 		- decrement age
+* 		- if age is 0 clear cell
+* 		- if cell has direction (i.e. snake head)
+* 			- if target cell is red (apple) increment age
+* 			- color new cell in direction:
+* 				- set age on to current age + 1
+* 				- set direction to current
+* 			- clear direction
+*
+* NOTE: that in the above description some details are omitted for 
+* 		clarity...
