## Events
All events (system and user defined) can be fired only when promises in pending state.

Predefined (system) events:
- `cancel(reason: CanceledError)` - fires when promise is canceled (rejected with `CanceledError`)
- `pause` - on promise pause request
- `resume` - on promise resume request
- `capture(scope: CPromise)` - fired when some consumer directly or above standing in the chain starts progress capturing
- `progress(value: Number, scope: CPromise, data: Object?)` - fired when promise chain progress changes

Event listener attaching shortcuts (methods bound to the promise instance):
- `onCancel(listener: Function)`
- `onPause(listener: Function)`
- `onResume(listener: Function)`
- `onCapture(listener: Function)`
