methods:
    emit('event', [arg1], [arg2], [...])
    deferEmit('event', [arg1], [arg2], [...])
    on('event', callback([arg1], [arg2], [...]))
    once('event', callback([arg1], [arg2], [...])) // run once
    remove([event])                                // remove one or all events
    listeners()                                    // return active events

Example

var EventEmitter = require('tiny-eventemitter');

var em = new EventEmitter();

em.on('hello', function (arg1, arg2) {
    console.log(arg1 + ' ' + arg2);
});

em.emit('hello', 'Hello', 'World');

em.remove('hello');




// Inherit from tiny-eventemitter

var inherits = require('util').inherits;   
var EventEmitter = require('tiny-eventemitter');



function DummyTest () {
  EventEmitter.call(this);
}

inherits(DummyTest, EventEmitter);

DummyTest.prototype.write = function (client, msg) {
  this.emit('msg', client, msg);
};


var dummy = new DummyTest();

console.log(dummy instanceof EventEmitter);
console.log(DummyTest.super_ === EventEmitter);


dummy.on('msg', function (client, msg) {
  console.log(client + ': ' + msg);
});

dummy.write(12, 'Hello World!!!');




// using an defer emitter

var em = new EventEmitter();

em.on('hello', function (arg) {
    console.log(arg);
});

process.nextTick(function () {
  console.log('nextTick => will call after "first" & "second" emits but before the "end" emitter');
});

// note: in this example put "process.nextTick" before purposely
// deferEmit must be declare/write/emit after "process.nextTick"
em.deferEmit('hello', 'this will be emit in end');

em.emit('hello', 'this will emit first');
em.emit('hello', 'this will emit in second');
