 Event data for an event that represents an input source being detected or lost.
 
-#### GestureManipulator.cs
-A component for moving an object via the GestureManager manipulation gesture.
-
-When an active GestureManipulator component is attached to a GameObject it will subscribe 
-to GestureManager's manipulation gestures, and move the GameObject when a ManipulationGesture occurs. 
-If the GestureManipulator is disabled it will not respond to any manipulation gestures. 
- 
-This means that if multiple GestureManipulators are active in a given scene when a manipulation 
-gesture is performed, all the relevant GameObjects will be moved.  If the desired behavior is that only 
-a single object be moved at a time, it is recommended that objects which should not be moved disable 
-their GestureManipulators, then re-enable them when necessary (e.g. the object is focused).
