    - Gestures Library Overview
      The Gestures library provides gesture recognizers to detect gestures through touch events that occur when you place one or more fingers on a touch screen.
    - Gesture Recognition
      Gesture recognition is performed by gesture recognizers that detect gestures through touch events.
    - User defined gestures
      You can define gesture recognizers to detect gestures that are not already supported by the Gestures library (custom gestures). Gesture recognizers that are used to detect custom gestures can be compiled with the application code and added to a gesture set in the same way that system gesture recognizers are added to a gesture set.
