* @name Scroll
* @description
* Scroll is a non-flexboxed scroll area that can scroll horizontally or vertically. `ion-Scroll` Can be used in places where you may not need a full page scroller, but a highly customized one, such as image scubber or comment scroller.
* @usage
* ```html
* <ion-scroll scrollX="true">
* </ion-scroll>
*
* <ion-scroll scrollY="true">
* </ion-scroll>
