/**
 * View, the V in the MVC triad. View interacts with Helpers and view variables passed
 * in from the controller to render the results of the controller action.  Often this is HTML,
 * but can also take the form of JSON, XML, PDF's or streaming files.
 *
 * CakePHP uses a two-step-view pattern.  This means that the view content is rendered first,
 * and then inserted into the selected layout.  This also means you can pass data from the view to the
 * layout using `$this->set()`
 *
 * Since 2.1, the base View class also includes support for themes by default.  Theme views are regular
 * view files that can provide unique HTML and static assets.  If theme views are not found for the
 * current view the default app view files will be used.  You can set `$this->theme = 'mytheme'`
 * in your Controller to use the Themes.
 *
 * Example of theme path with `$this->theme = 'SuperHot';` Would be `app/View/Themed/SuperHot/Posts`
