 Renders a star rating component.
 
+Use and IIFE to define a functional component, called `Star` that will render each individual star with the appropriate appearance, based on the parent component's `state` and return the class component `StarRating`.
 Use the value of the `rating` prop to determine if a valid rating is supplied and store it in `state.rating` (or `0` if invalid or not supplied).
 Initialize `state.selection` to `0`.
-Create two methods, `hoverOver` and `setRating`, that take a number as argument and update `state.selected` and `state.rating` according to it, bind them both to the component's context.
-Define a functional component, called `Star` that will render each individual star with the appropriate appearance, based on the parent component's `state`, and handle its `onMouseEnter` event, using the parent component's `hoverOver` method.
-In the `render()` method, create a `<div>` to wrap the `<Star>` components, which are created using `Array.prototype.map` on an array of 5 elements, created using `Array.from`, and handle the `onMouseLeave` event to set `state.selection` to `0` and the `onClick` event to set the `state.rendering` to the `star-id` attribute of the `event.target`. 
-Finally, pass the appropriate values to each `<Star>` component (`starId`, `marked` and `onHover`).
