 ## Program life cycle :
 - map parsing :

-	- verify map format`
-	- import map `into array
-	- save player pos
-	- verify map validy 
+	- [ ] read file,
+	- [ ] extract walls textures,
+	- [ ] extract sky and ceil colors
+	- [ ] import map into array,
+	- [ ] save player pos,
+	- [ ] handle errors,
 - initialize env
 - generate window
 - display view

 the map following the walls and never going on an already visited
 wall until you come back to starting pos.
