generator 0.2.0

# Generator-rs

rust generator library

use the dev version on master

```toml
[dependencies.generator]
git = "https://github.com/Xudong-Huang/generator-rs.git"
```


## Usage
```rust
#[macro_use]
extern crate generator;

fn main() {

    let g = generator::Gn::<()>::new(|| {
        let (mut a, mut b) = (0, 1);
        while b < 200 {
            std::mem::swap(&mut a, &mut b);
            b = a + b;
            _yield_!(b);
        }
        a + b
    });

    for i in g {
        println!("{}", i);
    }
}
```

## Output
```

## Goals

- [x] basic send/yield support
- [x] generator cancel support
- [x] yield_from support
- [x] panic inside genertor support
- [x] Basic single threaded support
- [x] compact stack support
- [ ] Multithreaded support



##  based on this basic library
- we can easily port python libary based on generator into rust. the libaray has more powerfull tools than python that can make the generator more fast, safe and multi thread support.
- schedule framework running with multi-thread.
- basic library for Asynchronous I/O
