/**
 * Base reactive classes: Flowable, Observable, Single and Completable; base reactive consumers;
 * other common base interfaces.
 *
 * <p>A library that enables subscribing to and composing asynchronous events and
 * callbacks.</p>
 * <p>The Flowable/Subscriber, Observable/Observer, Single/SingleObserver and
 * Completable/CompletableObserver interfaces and associated operators (in
 * the {@code io.reactivex.internal.operators} package) are inspired by the
 * Reactive Rx library in Microsoft .NET but designed and implemented on
 * the more advanced Reactive-Streams ( http://www.reactivestreams.org ) principles.</p>
 * <p>
 * More information can be found at <a
 * href="http://msdn.microsoft.com/en-us/data/gg577609">http://msdn.microsoft.com/en-us/data/gg577609</a>.
 * </p>
 *
 *
 * <p>Compared with the Microsoft implementation:
 * <ul>
 * <li>Observable == IObservable (base type)</li>
 * <li>Observer == IObserver (event consumer)</li>
 * <li>Disposable == IDisposable (resource/cancellation management)</li>
 * <li>Observable == Observable (factory methods)</li>
 * <li>Flowable == IAsyncEnumerable (backpressure)</li>
 * <li>Subscriber == IAsyncEnumerator</li>
 * </ul>
 * The Single and Completable reactive base types have no equivalent in Rx.NET as of 3.x.
 * </p>
 * <p>Services which intend on exposing data asynchronously and wish
 * to allow reactive processing and composition can implement the
 * {@link io.reactivex.Flowable}, {@link io.reactivex.Observable}, {@link io.reactivex.Single}
 * or {@link io.reactivex.Completable} class which then allow consumers to subscribe to them
 * and receive events.</p>
 * <p>Usage examples can be found on the {@link io.reactivex.Flowable}/{@link io.reactivex.Observable} and {@link org.reactivestreams.Subscriber} classes.</p>
