* Creates a token that can be used in a DI Provider.
*
* Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
* runtime representation) such as when injecting an interface, callable type, array or
* parameterized type.
*
* `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
* the `Injector`. This provides additional level of type safety.
*
* ```
* interface MyInterface {...}
* var myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
* // myInterface is inferred to be MyInterface.
* ```
*
* When creating an `InjectionToken`, you can optionally specify a factory function which returns
* (possibly by creating) a default value of the parameterized type `T`. This sets up the
* `InjectionToken` using this factory as a provider as if it was defined explicitly in the
* application's root injector. If the factory function, which takes zero arguments, needs to inject
* dependencies, it can do so using the `inject` function. See below for an example.
*
* Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
* overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
* mentioned above, `'root'` is the default value for `providedIn`.
