Displays the top tags/mentions/words from given input file as a word
cloud with font size of each item being proportional to its rank.  I
ended up using the code I had already started because I've been working
with OpenCloud.
Complete Except:
	-integrate Scott's code to allow user to specify file 
	-allow user to specify the number of top items to display (right now
set to 20)
	-add some css to make output more visually appealing
