A fast and lightweight event bus

Disclaimer: This was originally meant to be for Cosmos, because Linus thought that the FML Event Bus was an issue, when it wasn't. However, it turns out that this one is wayyyy faster than it, so yeah.

For example:

import cope.cosma.bus.EventBus;

public class Main {
    private static final EventBus EVENT_BUS = new EventBus();
    
    public static void main(String[] args) {
        // @todo add your code here
    }
}

The EVENT_BUS field is what we're worried about, here is all of the methods you need to know:

• subscribe(Ljava/lang/Object)V - Subscribes an object to the EventBus
• unsubscribe(Ljava/lang/Object)V - Removes a subscriber
• dispatch(Lcope/cosma/listener/Event)V - Dispatches an event to all subscribers

To create an event, do the following:

import cope.cosma.listener.Event;

// If you want to be able to cancel this event from emitting to other listeners, add a @Cancelable here!
public class MyEvent extends Event {
    private final long time;

    public MyEvent(long time) {
        this.time = time;
    }

    public long getTime() {
        return time;
    }
}

Then you can just post the event to the EventBus as follows:

Main.EVENT_BUS.dispatch(new MyEvent(System.currentTimeMillis()));

From dispatching the event to receiving the event, there was a 10-20ms delay on average.
