How-to

First, requires Jvent:

var Jvent = require('jvent');

Creates a new instance:

var emitter = new Jvent();

Now, defines a listener:

function listener(arg1, arg2) {
    alert(arg1 + ' '+ arg2);
})

Then, adds a new event live with a listener:

emitter.on('live', listener);

Emitsthe event with some data:

emitter.emit('live', 'param1', 'param2');
