Input

new Input()

Improvements and expansion of default Input to include multi touch and gestures.
- 1. instead of using ig.input.mouse, use ig.Input#inputPoints, ig.Input#getInputPoint, or ig.Input#getInputPoints
- good news everybody, ig.input.mouse is still updated for backwards compatibility Tip: mouse and touches are both treated as input points so you can use them the same way anywhere.
