ZingTouch.Expand doesn't emit any events

[hackhat]

const zingPinch = new ZingTouch.Pinch({});
const zingExpand = new ZingTouch.Expand({});
zingTouchActiveRegion.bind(this.canvasElement, zingExpand, (e) => {
  // never fired!
  alert(JSON.stringify(e.detail))
});
zingTouchActiveRegion.bind(this.canvasElement, zingPinch, (e) => {
  // fires on pinch!
});

Not sure why the Expand doesn't work but the Pinch works

But if I remove the pinch

zingTouchActiveRegion.bind(this.canvasElement, zingExpand, (e) => {
  alert(JSON.stringify(e.detail))
});

the event emitted is e.detail.distance instead of e.detail.expand as stated in the docs. https://zingchart.github.io/zingtouch/docs/#expand

This is a bug. See issue #45. I fixed this in PR #48 by consolidating Pinch, Expand, and Distance.
