2. One liner to stop/delete containers docker stop $(docker ps -a -q) docker rm $(docker ps -a -q)
3. Clean docker docker system prune deletes that are not associated with container

this._panResponder = PanResponder.create({
  // ----------- NEGOTIATION:
  // A view can become the touch responder by implementing the correct negotiation methods.

    // Should child views be prevented from becoming responder on first touch?
    onStartShouldSetPanResponderCapture: (evt, gestureState) => () => {
      console.info('onStartShouldSetPanResponderCapture');
      return true;
    },
