pbr 0.0.2

# Console progress bar for Rust

Console progress bar for Rust Inspired from [pb](http://github.com/cheggaaa/pb), support and 
tested on MacOS and Linux(should work on Windows too, but not tested yet).

### Examples
1. simple example

```rust
extern crate pbr;

use pbr::ProgressBar;
use std::thread;

fn main() {
    let count = 1000;
    let mut pb = ProgressBar::new(count);
    for _ in 0..count {
        pb.inc();
        thread::sleep_ms(200);
    }
    println!("done!");
}
```

2. Broadcast writing(simple file copying)

```rust
extern crate pbr;

use std::io::copy;
use std::fs::{self, File};
use pbr::{ProgressBar, Units};

fn main() {
    let fname = "/usr/share/dict/words";
    let mut file = File::open(fname).unwrap();
    let n_bytes = fs::metadata(fname).unwrap().len() as usize;
    let mut pb = ProgressBar::new(n_bytes);
    pb.set_units(pb::Units::Bytes);
    let mut dfile = File::create("copy-words").unwrap();
    let mut handle = dfile.broadcast(&mut pb);
    copy(&mut file, &mut handle).unwrap();
    println!("done!");
}
```
