A Disposable is a cancellation handler representing arbitrary long running work.

This library is used in the Emitter reactive streams library and internally within the StateTree framework.

A Disposable is intended to bridge different cancellable sources including:

• Combine's Cancellable's cancel()
• Swift's Task's cancel()

This package also provides a DisposableStage which allows for grouping Disposables and handling them as a single entity — i.e. as Combine uses Set<AnyCancellable> and RxSwift uses DisposeBag.
