PortAudio bindings for Rust

Example

```rust extern crate portaudio;

fn demo() -> portaudio::PaResult { let stream = try!(portaudio::stream::Stream::opendefault( 0, // input channels 1, // output channels 44100.0, // sample rate portaudio::stream::FRAMESPERBUFFERUNSPECIFIED, None // no callback ));

try!(stream.start());

let mut phase = 0.0f32;
let mut buffer = Vec::with_capacity(44100);
for _i in (0..44100)
{
    // Small amplitude such that the test does not produce sound
    buffer.push(phase * 0.001);

    phase += 0.03;
    if phase > 1.0 { phase -= 2.0; }
}

try!(stream.write(&buffer));

Ok(())

}

fn main() { portaudio::initialize().unwrap(); println!("{:?}", demo()); portaudio::terminate().unwrap(); } ```
