 * CancellableReporter is a reporter mainly for internal use by the suite runner. It
 * forwards all messages to another reporter, except for when it's been
 * "cancelled". When the CancellableReporter is cancelled, it will emit "aborted" finish
 * messages for all currently running tests and then ignore all subsequent
 * messages.
 *
 * This is used in the suite runner to be able to implement cancellation in a
 * nice way that doesn't require everything to know about cancellation.
