     * @param {Function|string} constructor If called with a function then it's considered to be the
     *    controller constructor function. Otherwise it's considered to be a string which is used
     *    to retrieve the controller constructor using the following steps:
     *
     *    * check if a controller with given name is registered via `$controllerProvider`
     *    * check if evaluating the string on the current scope returns a constructor
     *
     *    The string can use the `controller as property` syntax, where the controller instance is published
     *    as the specified property on the `scope`; the `scope` must be injected into `locals` param for this
     *    to work correctly.
     *
     * @param {Object} locals Injection locals for Controller.
     * @return {Object} Instance of given controller.
     *
     * @description
     * `$controller` service is responsible for instantiating controllers.
     *
     * It's just a simple call to {@link auto.$injector $injector}, but extracted into
     * a service, so that one can override this service with [BC version](https://gist.github.com/1649788).
