/*  PHP RSS Reader v1.1
    By Richard James Kendall 
    Bugs to richard@richardjameskendall.com 
    Free to use, please acknowledge me 
    
    Place the URL of an RSS feed in the $file variable.
   	
   	The $rss_channel array will be filled with data from the feed,
   	every RSS feed is different by by and large it should contain:
   	
   	Array {
   		[TITLE] = feed title
   		[DESCRIPTION] = feed description
   		[LINK] = link to their website
   		
   		[IMAGE] = Array {
   					[URL] = url of image
   					[DESCRIPTION] = alt text of image
   				}
   		
   		[ITEMS] = Array {
   					[0] = Array {
   							[TITLE] = item title
   							[DESCRIPTION] = item description
   							[LINK = a link to the story
   						}
   					.
   					.
   					.
   				}
   	}
   	
   	By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array
   	structure so you can format the information as you see fit.
