//newsAjax 0.4 written by Ryan Senese for King's College
//This javascript operates by building an array of all list-elements (li) contained within the table cell, "BodyText". Once the array is built, we can manipulate it to display however we want.
//By default, if no parameters are passed to the function newsAjax, it will create a list of the latest six press releases; 5 in the "lastest press releases" list and one featured article for the newest press release.
//The first parameter, 'items' controls how many items appear in the "latest press releases" area. By default it is 5, but it can be changed to whatever you want (not exceeding the amount of list elements, obviously)
//The second parameter, 'featured' toggles the featured article area. If you pass a value of 0 through, it will be omitted from the page.
//In order for this to function properly, the HTML on the news pages MUST BE FORMATTED CORRECTLY! Do not use <br> tags or &nbsp; use <p> tags liberally for each paragraph of text.
//ADDED FUNCTIONALITY IN V0.2 - An ajax script feeds in the first image inside td.BodyText and rebuilds it with the appropriate aspect ratio for the Featured Article area.
//ADDED FUNCTIONALITY IN V0.3 - The image script now works in all supported browsers, and doesn't rely on width or height attributes. The resizing script will not allow for enormously huge heights anymore.
//ADDED FUNCTIONALITY IN V0.4 - Alt text and image source will now be converted to proper html in order to avoid single-quote catastrophes.
