/****************************************** Document on click **************************************************
Usage:  To add this functionality 
        appendtoClickList(refference of div/span object)
        
        if that object was closed because of document.onclick then this will raise an event called  close event , in order to use this functionality
        eg:
        <div id=test onclose="ur functionname alone don't use '()' ">
        that function should have 1 parameter 
        eg:
            <div id=test onclose="CallMeOnClose">
            appendtoClickList(document.getElementById('test'))
