New creates and returns a Chaosmonkey, with which the caller should register Tests and call Do.

Chaosmonkey is the type that holds the necessary content for chaosmonkey test.

Semaphore is taken by a Test and provides: Ready(), for the Test to call when it's ready for the disruption to start; and StopCh, the closure of which signals to the Test that the disruption is finished.

Interface can be implemented if you prefer to define tests without dealing with a Semaphore.

Disruption is the type to construct a Chaosmonkey with; see Do for more information.

Test is the type to register with a Chaosmonkey.
