A bencode parser.
```rust use bencodex::{BDict, BNode};
let mut dict = BDict::new(); dict.insert("bar".tostring(), "spam".into()); dict.insert("foo".tostring(), 42.into());
let bnode = BNode::Dict(dict);
let mut file = File::create( env::current_dir().unwrap().join("name.torrent") ).unwrap(); bnode.serialize(&mut file).unwrap(); ```
