   * the first argument to the callback.

   *   document.getElementById('modernizr2').style.width === '2px'; // true
   *   elem.firstChild === document.getElementById('modernizr2'); // true

   * ```
   *
   * By default, all of the additional elements have an ID of `modernizr[n]`, where
   * `n` is its index (e.g. the first additional, second overall is `#modernizr2`,
   * the second additional is `#modernizr3`, etc.).
   * If you want to have more meaningful IDs for your function, you can provide

   *
   * ```js
   * Modernizr.testStyles('#foo {width: 10px}; #bar {height: 20px}', function(elem) {
   *   elem.firstChild === document.getElementById('foo'); // true

Indicates if the browser supports the W3C Touch Events API.

This *does not* necessarily reflect a touchscreen device:

* Older touchscreen devices only emulate mouse events
* Modern IE touch devices implement the Pointer Events API instead: use `Modernizr.pointerevents` to detect support for that
* Some browsers & OS setups may enable touch APIs when no touchscreen is connected
* Future browsers may implement other event models for touch interactions

See this article: [You Can't Detect A Touchscreen](http://www.stucox.com/blog/you-cant-detect-a-touchscreen/).

It's recommended to bind both mouse and touch/pointer events simultaneously – see [this HTML5 Rocks tutorial](http://www.html5rocks.com/en/mobile/touchandmouse/).

This test will also return `true` for Firefox 4 Multitouch support.
