auto.$provide.decorator()

decorator(name, decorator);

Register a service decorator with the $injector. A service decorator intercepts the creation of a service, allowing it to override or modify the behavior of the service. The object returned by the decorator may be the original service, or a new service object which replaces or wraps and delegates to the original service.

The function is called using the injector.invoke method and is therefore fully injectable. Local injection arguments: `$delegate` - The original service instance, which can be monkey patched, configured, decorated or delegated to.
