// A TitanTV redesign has made this script obsolete.  As I find myself using
// TitanTV less and less since the school year began, I do not intend to 
// update it.  In its place, I recommend using "Remove ads from TitanTv" which
// does much of what this script did.

// @namespace      http://freecog.net/2006/
// @description    Removes ads and excess chrome from the TitanTV grid.  Also restyles the listings table to be a bit more low-key.  (I could use some help from a real designer here, my color scheme isn't much of an imrovement.)  Grid listings are given logical class names, so targeting them from userContent.css should be much easier (again, if you have a good color scheme, please contact me!).  Finally, listings are filtered based on their text content (you will likely want to edit this part to your tastes).
