/**
* Bootstrapping for Angular applications.
*
* You instantiate an Angular application by explicitly specifying a component to use
* as the root component for your application via the `bootstrap()` method.
*
* ## Simple Example
*
* Assuming this `index.html`:
*
* ```html
* <html>
* <!-- load Angular script tags here. -->
* <body>
* <my-app>loading...</my-app>
* </body>
* </html>
* ```
*
* An application is bootstrapped inside an existing browser DOM, typically `index.html`.
* Unlike Angular 1, Angular 2 does not compile/process providers in `index.html`. This is
* mainly for security reasons, as well as architectural changes in Angular 2. This means
* that `index.html` can safely be processed using server-side technologies such as
* providers. Bindings can thus use double-curly `{{ syntax }}` without collision from
* Angular 2 component double-curly `{{ syntax }}`.
*
* We can use this script code:
*
* {@example core/ts/bootstrap/bootstrap.ts region='bootstrap'}
*
* When the app developer invokes `bootstrap()` with the root component `MyApp` as its
* argument, Angular performs the following tasks:
*
* 1. It uses the component's `selector` property to locate the DOM element which needs
* to be upgraded into the angular component.
* 2. It creates a new child injector (from the platform injector). Optionally, you can
* also override the injector configuration for an app by invoking `bootstrap` with the
* `componentInjectableBindings` argument.
* 3. It creates a new `Zone` and connects it to the angular application's change detection
* domain instance.
* 4. It creates an emulated or shadow DOM on the selected component's host element and loads the
* template into it.
* 5. It instantiates the specified component.
* 6. Finally, Angular performs change detection to apply the initial data providers for the
* application.
*
*
* ## Bootstrapping Multiple Applications
*
* When working within a browser window, there are many singleton resources: cookies, title,
* location, and others. Angular services that represent these resources must likewise be
* shared across all Angular applications that occupy the same browser window. For this
* reason, Angular creates exactly one global platform object which stores all shared
* services, and each angular application injector has the platform injector as its parent.
*
* Each application has its own private injector as well. When there are multiple
* applications on a page, Angular treats each application injector's services as private
* to that application.
*
* ## API
*
* - `appComponentType`: The root component which should act as the application. This is
* a reference to a `Type` which is annotated with `@Component(...)`.
* - `customProviders`: An additional set of providers that can be added to the
* app injector to override default injection behavior.
*
* Returns a `Promise` of {@link ComponentRef}.
