Lapin integration with tokio

This crate integrates lapin with tokio by using tokio's executor inside of lapin for its internal operations and for consumer delegates.

``` use tokio_amqp::*; use lapin::{Connection, ConnectionProperties, Result}; use std::sync::Arc; use tokio::runtime::Runtime;

async fn tokiomain() -> Result<()> { let addr = std::env::var("AMQPADDR").unwraporelse(|| "amqp://127.0.0.1:5672/%2f".into()); let conn = Connection::connect(&addr, ConnectionProperties::default().withtokio()).await?; // Note the with_tokio() here let channel = conn.create_channel().await?;

// Rest of your program

}

fn main() { let rt = Runtime::new().expect("failed to create runtime"); rt.blockon(tokiomain()).expect("error"); } ```
