/**
 * Class Post
 *
 * This is the object you use to access or extend WordPress posts. Think of it as Timber's (more
 * accessible) version of `WP_Post`. This is used throughout Timber to represent posts retrieved
 * from WordPress making them available to Twig templates. See the PHP and Twig examples for an
 * example of what it’s like to work with this object in your code.
 *
 * @api
 * @example
 *
 * **single.php**
 *
 * ```php
 * $context = Timber::context();
 *
 * Timber::render( 'single.twig', $context );
 * ```
 *
 * **single.twig**
 *
 * ```twig
 * <article>
 *     <h1 class="headline">{{ post.title }}</h1>
 *     <div class="body">
 *         {{ post.content }}
 *     </div>

 * <article>
 *     <h1 class="headline">The Empire Strikes Back</h1>
 *     <div class="body">
 *         It is a dark time for the Rebellion. Although the Death Star has been
 *         destroyed, Imperial troops have driven the Rebel forces from their
 *         hidden base and pursued them across the galaxy.
