            The Rating control provides an intuitive rating experience that allows users to select the number
            of stars that represents their rating.  The page designer can specify the initial rating, the
            maximum rating to allow, the alignment and direction of the stars, and custom styles for the
            different states a star can have.  Rating also supports a ClientCallBack event that allows custom
            code to run after the user has rated something.
