Xy Ozys
=======
Aka. Tic-Tac-Toe, Noughts and Crosses etc.
## Challenge
Implement a library which enables playing games of Xy Ozys.
### Rules
* Expose similar API to that defined in the _Spec_, however you may diverge for lang idiom reasons.
* Implement using [functional programming](https://en.wikipedia.org/wiki/Functional_programming).
* Write tests for the public API.
## Spec
### Functions
Start a new game:
```
new() # => Game
```
Player makes a move:
```
turn(Game, Cell, Player) # => Ok(Game) | Error(Reason)
```
Query the game state:
```
status(Game) # => Status
```
### Types
```
Game # Reference to the game
Cell # Reference to a position within the game board
Player # 'X' or 'O'
Status # "Tie", "X Wins", "O Wins", "X's Turn", "O's Turn"
Reason # Reason that `turn` operation was invalid e.g. "Game over", "Not X's turn" etc.
```
