Api should work like Node.js EventEmitter on both client and server.

Overview:

• EventEmitter
• setMaxListeners(n)
• on(eventName, listener)
• once(eventName, listener)
• emit(eventName /* arguments */)
• off(eventName, listener)

Wrapper apis node js like:

• addListener(eventName, listener)
• removeListener(eventName, listener)
• removeAllListeners(eventName, listener)

Wrapper apis jQuery like:

• one(eventName, listener)
• trigger(eventName /* arguments */)

Tests are covered and will be extended as issues demand.

Creating EventEmitter object

Meteor.isClient() {
    Event = new EventEmitter();
}

Emitting event

Event.emit('customEvent', {
    data: bar
});

Listening the event (at a template for instance)

var listener;
Template.example.created = function() {
    listener = function(bar) {
        console.log('Listening custom event', bar);
    };
    Event.on('customEvent', listener);
}

Template.example.destroyed = function() {
    Event.removeListener('customEvent', listener);
}
