Instance Method Summary
	`decorateInternal(?Element el)` Decorate a HTML structure already in the document. Expects the structure: - div - select - option 1 #text = 1 star - option 2 #text = 2 stars - option 3 #text = 3 stars - option N (where N is max number of ratings) The div can contain other elements for graceful degredation, but they will be hidden when the decoration occurs.
	`disposeInternal()` Disposes of the component. Calls {@code exitDocument}, which is expected to remove event handlers and clean up the component. Propagates the call to the component's children, if any. Removes the component's DOM from the document unless it was decorated.
	`enterDocument()` Render the rating widget inside the provided element. This will override the current content of the element.
	`exitDocument()` Should be called when the widget is removed from the document but may be reused. This removes all the listeners the widget has attached and destroys the DOM nodes it uses.
	`getAttachedFormField() ⇒ (HTMLInputElement\|HTMLSelectElement\|null)` Returns the attached input or select element to the ratings widget.
	`getClassName_(number i, boolean on) ⇒ string` Get the class name for a given rating. All stars have the class: goog-ratings-star.
