 * The Post component that Mars uses to render any kind of "post type", like

 * {@link connect}. The current Frontity state is used to know which post type
 * should be rendered.
 *
 * @param props - The Frontity store (state, actions, and libraries).
 *
 * @example
 * ```js
 * <Switch>
 *   <Post when={data.isPostType} />
 * </Switch>
 * ```
 *
 * @returns The {@link Post} element rendered.
