/** This script calls a php script which attempts to find the rating/votes of the current movie. 
 ** For those of you wondering whether a movie is good enough to rent, this is for you.
 ** Also, it should be helpful when browsing /AllNewReleases as there are many that you may
 ** want to check. I am not sure how much bandwidth this script will take up, but if anyone
 ** has a better host to host the remote script on, any help would be appreciated.
 **
 ** This script is losely based on, and is in complement to, "Netflix Links in IMDb"
 **  http://www.artefxdesign.com/greasemonkey
 **
 ** This in turn is also based on "IMDb Links in Netflix" 
 **  http://www.j-san.net/code/greasemonkey
 ** 
 ** for questions, bugs, compliments, etc.: http://www.hulkmad.com/greasemonkey
 **
 ** This is a greasemonkey script, intended for use with the Firefox extension Greasemonkey.
