trait Cancellable extends AnyRef
Defines a trait that makes the underlying object *cancellable*. Cancellable objects may be linked to each other (one way) in order to propagate cancellation.
Note that the underlying object may or may not _respond_ to the cancellation request. That is, calling 'cancel()' does not guarantee the cancellation of the computation; rather it is a hint that the provider of the computation may choose to ignore.

Abstract Value Members
- abstract def cancel(): Unit
Cancel the computation.
Cancel the computation. The cancellation is propagated to linked cancellable objects.
- abstract def isCancelled: Boolean
- abstract def linkTo(other: Cancellable): Unit
Link this cancellable computation to 'other'.
Link this cancellable computation to 'other'. This means cancellation of 'this' computation will propagate to 'other'.
