This will be part of public API and needs a richer documentation with an example.

@Injectable() supports a scope parameter which specifies the target module. However, it's still difficult to specify that a particular service belongs in the root injector. A developer attempting to ensure that must either also provide a module intended for placement in the root injector or target a module known to already be in the root injector (e.g. BrowserModule). Both of these strategies are cumbersome and brittle. Instead, this commit adds a token APP_ROOT_SCOPE which provides a straightforward way of targeting the root injector directly, without requiring special knowledge of modules within it.
