/**
 * QUÉ ES ESTO
 * Una manera muy simple de organizar los eventos de una página de tal modo que no están
 * esparcidos por el código javascript. Inspirado en las vistas de backbone.js
 * 
 * POR QUÉ
 * De este modo los eventos que escucha tu página están declarados en un lugar evidente.
 * 
 * CÓMO USARLO
 * Crea una clase View que herede de AbstractView. Esta clase debe definir:

class @AbstractView
  constructor: ->
    console.log "I'm not meant to be instantitated"

  render: ->
    for event_selector of @events
      event_selector_array = event_selector.split(' ')
      event = event_selector_array.reverse().pop()
      selector = event_selector_array.reverse().join(' ')
      if selector == 'document'

/**
 * Clase de ejemplo o referencia para usarse con AbstractView.
 */
 
 View = (function(_super) {
  __extends(View, _super);

  function View() {
    return View.__super__.constructor.apply(this, arguments);

RxJS and Bacon.js equivalences:

	Bacon.js	RxJS
Create stream for keyup events from an element	var inputText$ = $([data-js=my-input]).asEventStream('keyup').map('.target.value');	var inputText$ = Rx.Observable.fromEvent($('[data-js=my-input]'), 'keyup').pluck('target', 'value')
Create stream for keyup events from a live element	var inputText$ = $(document).asEventStream('keyup', '[data-js=my-input]').map('.target.value');	var inputText$ = Rx.Observable.create(function(observer) {$(document).on('keyup', '[data-js=my-input]', function(e) {observer.onNext(e.target.value);});});
Subscribe to a stream	inputText$.onValue(function(props) {…});	inputText$.subscribe(function(props) {…});
Create stream from promises	Bacon.fromPromise($.get(url, {text: text}));	Rx.Observable.fromPromise($.get(url, {text: text}));
