## Windows 8 IE include
Now you can use the swipeJS in Windows8. (Support MSPointer events)
## Usage
Swipe only needs to follow a simple pattern. Here is an example:

`getNumSlides()` returns the total amount of slides

`slide(index, duration)` slide to set index position (duration: speed of transition in milliseconds)

## Browser Support
Swipe is now compatible with all browsers, including IE7+. Swipe works best on devices that support CSS transforms and touch, but can be used without these as well. A few helper methods determine touch and CSS transition support and choose the proper animation methods accordingly.
