Connect Four Project Interaction pattern

Class
  Board
-creates board cells
-renders board

-Is created by cells. Can accept “X” or  “O”  
(default/empty space  = “.”)

Winner Method
-recognizes 4 chips in a row (cells with x or o)  in a row horizontal, vertical or diagonal 

Vertical win method
Array.transpose will return a new array from
 index[0] of nestled(?) arrays. Then check index # for value
		If 4 in a row == win
			How to check for 4 in a row, within an array	
Horizontal win method
		How to check horizontal win?
	4 in a row within an array == win
(maybe use vertical win array method above)
	
Diagonal win method
How to check for diagonal win?
			?
Draw method
If board is full && no win then game is draw

		Cell class?(maybe in board class) + tests
		-is cell open? (“.”) or taken (“x” or “o”)
		-Chip needs to go in a column
-Placement. Chip needs to go in lowest cell
			Chip cannot float


			

  Player
-Player 1(user)
Player class -Selecting column a-g input only
	Other than A-G is invalid input
- Player2/computer(computer generated play that is randomized)


  Game
	
42 =max number of rounds/plays 

Other necessary messages + output
	“You won!” etc?
	
	
Runner
