/**
 * Layout container component.
 * When using with Nebular Theme System it is required that all child components should be placed inside.
 *
 * Basic example of two column layout with header:
 *
 * @stacked-example(Showcase, layout/layout-showcase.component)
 *
 * Can contain the following components inside:
 *
 * ```html
 * <nb-layout>
 *  <nb-layout-header></nb-layout-header>
 *  <nb-layout-footer></nb-layout-footer>
 *  <nb-layout-column></nb-layout-column>
 *  <nb-sidebar></nb-sidebar>
 * </nb-layout>
 * ```
 * ### Installation
 *
 * Import `NbLayoutModule.forRoot()` to your app module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbLayoutModule.forRoot(),
 *   ],
 * })
 * export class AppModule { }
 * ```
 * and `NbLayoutModule` to your feature module where the component should be shown:
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbLayoutModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 * By default the layout fills up the whole view-port.
 * The window scrollbars are disabled on the body and moved inside of the nb-layout, so that the scrollbars
 * won't mess with the fixed nb-header.
 *
 * The child components are projected into a flexible layout structure allowing to adjust the layout behavior
 * based on the settings provided.
 *
 * The layout content (columns) becomes centered when the window width is more than
 * the value specified in the theme variable `layout-content-width`.
 *
 * The layout also contains the area on the very top (the first child of the nb-layout), which could be used
 * to dynamically append some components like modals or spinners/loaders
 * so that they are located on top of the elements hierarchy.
 * More details are under the `ThemeService` section.
 *
 * The layout component is also responsible for changing application themes.
 * It listens to the `themeChange` event and change a theme CSS class appended to body.
 * Based on the class appended, specific CSS-theme is applied to the application.
 * More details of the Theme System could be found here [Enabling Theme System](#/docs/concepts/theme-system)
 *
 * A simple layout with footer:
 *
 * @stacked-example(Layout With Footer, layout/layout-w-footer.component)
 *
 * It is possible to ask the layout to center the columns (notice: we added a `center` attribute
 * to the layout:
 *
 * ```html
 * <nb-layout center>
 *   <nb-layout-header>Awesome Company</nb-layout-header>
 *
 *   <nb-layout-column>
 *     Hello World!
 *   </nb-layout-column>
 *
 *   <nb-layout-footer>Contact us</nb-layout-footer>
 * </nb-layout>
 * ```
