 #### `defaultLayout`
-The string name or path of a template in the `layoutsDir` to use as the default layout. This is overridden by a `layout` specified in the app or response `locals`. **Note:** A falsy value will render without a layout; e.g., `res.render('home', {layout: false});`.

 #### `helpers`
 An object which holds the helper functions used when rendering templates with this `ExpressHandlebars` instance. When rendering a template, a collection of helpers will be generated by merging: `handlebars.helpers` (global), `helpers` (instance), and `options.helpers` (render-level). This allows Handlebars' `registerHelper()` function to operate as expected, will providing two extra levels over helper overrides.
