  /**
   * The Max operator operates on an Observable that emits numbers (or items that can be compared with a provided function),
   * and when source Observable completes it emits a single item: the item with the largest value.
   *
   * <img src="./img/max.png" width="100%">
   *
   * @example <caption>Get the maximal value of a series of numbers</caption>
   * Rx.Observable.of(5, 4, 7, 2, 8)
   *   .max()
   *   .subscribe(x => console.log(x)); // -> 8
   *
   * @example <caption>Use a comparer function to get the maximal item</caption>
   * interface Person {
   *   age: number,
   *   name: string
   * }
   * Observable.of<Person>({age: 7, name: 'Foo'},
   *                       {age: 5, name: 'Bar'},
   *                       {age: 9, name: 'Beer'})
   *           .max<Person>((a: Person, b: Person) => a.age < b.age ? -1 : 1)
   *           .subscribe((x: Person) => console.log(x.name)); // -> 'Beer'
   * }
   *
   * @see {@link min}
   *
   * @param {Function} [comparer] - Optional comparer function that it will use instead of its default to compare the
   * value of two items.
   * @return {Observable} An Observable that emits item with the largest value.
