    addObserverMethods

The function adds everything that is needed to an object. It will get a event-callbacks-map, an observer/listener method (on)
and a trigger method (fire).
Usage

  var obj = {
    walk: function() {
      // do smth
      this.fire('walk')
    }
  }

  addObserverMethods(obj)

  obj.on('walk', function() {
    alert('it moved!')
  })

  obj.walk()
Or use it with a prototype:
  var Player = function(){
    addObserverMethods(this)
  }

  Player.prototype.walk = function() {
    // do smth
    this.fire('walk')
  }

  var player = new Player()
  player.on('walk', function() {
    alert('it moved!')
  })
  player.walk()

  
## annotated.js
function(
  a // an object / instance
) {
  a.l = {};                 // eventName - listeners - map
  a.on = function(          // the observer method
    b,                      // the event name
    c                       // the callback
  ) {
    a.l[b] = a.l[b] || [];  // init array for current event name
    a.l[b].push(c)          // save callback for the event name
  };
  a.fire = function(        // the trigger method
    b                       // the event name
  ) {
    // iterate over the event name's callbacks and exec them
    (a.l[b] || []).forEach(function(a) {
      a()
    })
  }
}

## index.js
