Eases in a strong fashion either at the beginning (easeIn), the end (easeOut), or both (easeInOut). Expo is a convenience class that congregates the 3 types of Expo eases (ExpoIn, ExpoOut, and ExpoInOut) as static properties so that they can be referenced using the standard synatax, like Expo.easeIn, Expo.easeOut, and Expo.easeInOut.
