Console progress bar for Rust

Console progress bar for Rust Inspired from 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!"); } ```

1. 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 nbytes = fs::metadata(fname).unwrap().len() as usize; let mut pb = ProgressBar::new(nbytes); 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!"); } ```
