EventDispatcher

A simple library to register listeners for specific events inspired by rust-emitter.

Usage example

```rust extern crate event_dispatcher;

use event_dispatcher::{Event, Listener, Dispatcher, Dispatchable};

struct TestEvent { stopped: bool, data: String }

impl TestEvent { pub fn new(eventdata: String) -> TestEvent { TestEvent { stopped: false, data: eventdata } } }

impl Event for TestEvent { fn ispropagationstopped(&self) -> bool{ self.stopped }

fn stop_propagation(&mut self){
    self.stopped = true;
}

}

// the listener fn eventtest(event: &TestEvent) { println!("called \"eventtest\""); }

fn main() { let event = TestEvent::new("myevent".tostring()); let mut dispatcher = Dispatcher::new(); dispatcher.addlistener(&event, Listener::new(myevent_test));

dispatcher.dispatch(&event);

}

```
