// 	Widget that provides useful/common functionality that may be desirable
// 	when interacting with ul/ol html lists.

// The core behaviour of the lists this widget manages is expected to be determined
// by the css class names defined: 
// 	
// 	 "radioGroup" - Applied to main ol or ul 
//	 "selected"	- Applied to the currently selected li, if any.
//   "itemContent" - Applied to the content contained in a li, this widget embeds a span 
//					within each <li></li> to contain the contents of the li.
// This widget was mostly developed under supervision/guidance from Tom Trenka.
