special YUI library DOM event, see http://developer.yahoo.com/yui/event/#onavailable
onAvailable lets you define a function that will execute as soon as an element is
detected in the DOM. The intent is to reduce the occurrence of timing issues when
rendering script and html inline. It is not meant to be used to define handlers for
elements that may eventually be in the document; it is meant to be used to detect
elements you are in the process of loading.
