Changed .php file name to make it more specific toward its function and to differentiate it from the .php file for the search cloud
Alright, alright, alright...getting the ball rollin' here
Got the keyword search to create a cloud.  The tags display the user name, as well as a formatted date
I'm not finished with the search cloud...but I'm starting to
see that my code looks like a bunch of functions strewn about and tied
together in difficult to understand ways.  I want to take a bit of time to
refactor everything into a more object-oriented style.  When I'm finished
doing that, I'll return to finish the keyword search cloud.
