/**
* Represents all of the notifications from the source Observable as `next`
* emissions marked with their original types within {@link Notification}
* objects.

* <img src="./img/materialize.png" width="100%">
* `materialize` returns an Observable that emits a `next` notification for each
* `next`, `error`, or `complete` emission of the source Observable. When the
* source Observable emits `complete`, the output Observable will emit `next` as
* a Notification of type "complete", and then it will emit `complete` as well.
* When the source Observable emits `error`, the output will emit `next` as a
* Notification of type "error", and then `complete`.
* This operator is useful for producing metadata of the source Observable, to
* be consumed as `next` emissions. Use it in conjunction with
* {@link dematerialize}.
* @example <caption>Convert a faulty Observable to an Observable of Notifications</caption>
* var letters = Rx.Observable.of('a', 'b', 13, 'd');
* var upperCase = letters.map(x => x.toUpperCase());
* var materialized = upperCase.materialize();
* materialized.subscribe(x => console.log(x));
* // Results in the following:
* // - Notification {kind: "N", value: "A", error: undefined, hasValue: true}
* // - Notification {kind: "N", value: "B", error: undefined, hasValue: true}
* // - Notification {kind: "E", value: undefined, error: TypeError:
* // x.toUpperCase is not a function at MapSubscriber.letters.map.x
* // [as project] (http://1…, hasValue: false}
* @see {@link Notification}
* @see {@link dematerialize}
* @return {Observable<Notification<T>>} An Observable that emits
* {@link Notification} objects that wrap the original emissions from the source
* Observable with metadata.
