	Currently implemented in <Fx.Base>, <XHR> and <Ajax>. In <Fx.Base> for example, is used to execute a list of function, one after another, once the effect is completed.

	The functions will not be fired all togheter, but one every completion, to create custom complex animations.



Example:

	(start code)

	myFx.start(1,0).chain(function(){

		myFx.start(0,1);

Class: Events

	An "Utility" Class. Its methods can be implemented with <Class.implement> into any <Class>.

	In <Fx.Base> Class, for example, is used to give the possibility add any number of functions to the Effects events, like onComplete, onStart, onCancel.

	Events in a Class that implements <Events> can be either added as an option, or with addEvent. Never with .options.onEventName.



Example:

	(start code)

Note:

	if you load <Element.Selectors.js>, $$ will also accept CSS Selectors, otherwise the only selectors supported are tag names.



Example:

	>$$('a') //an array of all anchor tags on the page

	>$$('a', 'b') //an array of all anchor and bold tags on the page

	>$$('#myElement') //array containing only the element with id = myElement. (only with <Element.Selectors.js>)

	>$$('#myElement a.myClass') //an array of all anchor tags with the class "myClass"

	>//within the DOM element with id "myElement" (only with <Element.Selectors.js>)

	>$$(myelement, myelement2, 'a', ['myid', myid2, 'myid3'], document.getElementsByTagName('div')) //an array containing:

	>// the element referenced as myelement if existing,

	>// the element referenced as myelement2 if existing,

	>// all the elements with a as tag in the page,

	>// the element with id = myid if existing

	>// the element with id = myid2 if existing

	>// the element with id = myid3 if existing

	>// all the elements with div as tag in the page
