* @usage: Any HTML element with the class "gt-ratings-meter" will have a meter inserted. The element must be EMPTY except
* for the rating (from 0 - 10) as the contents of the div. A non-numerical value or value outside this range
* will be ignored.
*
* Additional parameters may be set to affect the size, duration, and framerate of the animated meter.
*
* Example:
*
* ex1:
* <div class="gt-ratings-meter">8.4</div>
*
* ex2:
* <div class="gt-ratings-meter"
* data-gt-ratings-size="90"
* data-gt-ratings-duration="1000"
* data-gt-ratings-fps="60">6.8</div>
