Prevent swiping when first or last page

[Mokto]

Hi,

It would be nice that we could prevent the user to swipe right on the last page and left on the first page.

Thanks.

In componentWillMount it is possible to add those extra tests

if (relativeGestureDistance < -0.25 || (relativeGestureDistance < 0 && vx <= -0.25)) {
        if (this.state.index < this.props.children.length - 1) { // make sure it is not the last page before incrementing
          newIndex += 1;
        }
} else if (relativeGestureDistance > 0.25 || (relativeGestureDistance > 0 && vx >= 0.25)) {
      if (this.state.index > 0) { // make sure it is not the first page before decrementing
          newIndex -= 1;
      }
}
