/*
 *
 *	IWE getnews
 *	You must use it together with AJAX object included in iwe_calendar.js package
 *	(so you must include this after that script)
 *	To allow also news ticker to work remember to include jquery-1.2.6.pack.js
 *	and jquery.accessible-news-slider.js (for automatic slide use the Alessandro Perrone
 *	customized version)
 *
 *	Remember to change the line in startSlider() to maintain JQuery compatibility if you are using also the prototype.js library
 *	If this is the case, remember to add the following line in a <script> tag before including the prototype.js library:
 *	JQ = jQuery.noConflict();
 *	Obviously, JQ is the same global variable you will use in startSlider() to initialize the slider
