Asynchronous TLS/SSL streams for futures using
[Rustls](https://github.com/ctz/rustls).

### Basic Structure of a Client

```rust
use webpki::DNSNameRef;
use futures_rustls::{ TlsConnector, rustls::ClientConfig };

// ...

let mut config = ClientConfig::new();
config.root_store.add_server_trust_anchors(&webpki_roots::TLS_SERVER_ROOTS);
let config = TlsConnector::from(Arc::new(config));
let dnsname = DNSNameRef::try_from_ascii_str("www.rust-lang.org").unwrap();

let stream = TcpStream::connect(&addr).await?;
let mut stream = config.connect(dnsname, stream).await?;

// ...
```
