     * so that no further processing is used. If the result is only one
     * entity a object is returned, otherwise a array of objects.

     * ```typescript
     *  const russell = await o('https://services.odata.org/TripPinRESTierService/')

     * @returns Either an array or a object with the given entities. If multiple
     *          resources are fetched, this method returns a array of array/object. If there
     *          is no content (e.g. for delete) this method returns the Response
