goban 0.8.2

# Goban

**Library to play with a rusty goban** 

**Use the version > 5.0 because in a bug detecting dead stones and in Ko detection**

*Channel : stable*

Only contains move generation, and rules there is no IA, neither
front-end.

rust cargo features: 
- thread-safe # for using Arc instead of Rc. decrease perfs.
- history     # each game will have his all history so you can iterate over it. decrease perfs.

Thanks to some help in profiling and optimisation we can run a playout radomly of an entire game in 28ms (before it was 600ms) ! 


Exemple :

```{rust}
use crate::goban::rules::*;
use crate::goban::rules::game::*;
use rand::seq::IteratorRandom;

let mut g = Game::new(GobanSizes::Nine, Rule::Chinese);
let mut i = 35;
while !g.over() && i != 0 {
   g.play(
        // legals return an iterator on (x,y) points
       g.legals()
           .choose(&mut rand::thread_rng())
           .map(|point| Move::Play(point.0,point.1))
           .unwrap());
   i -= 1;
   println!("{}", g);
}
```

## What works
- Capturing stones
- Playing
- Passing
- Resigning
- Implementation to count points
- Printing an *pretty* unicode Board on the terminal !
- SGF Import
- Generate legals moves (Handling Ko detection, Suicide moves, Super ko)
- Japanese Rules
- Chinese Rules

## What is not in point:
- Handling dead stones at the end of the game.

## Actively developed 
- Iterate over the game and history
