   * addTest allows you to define your own feature detects that are not currently

   * uses for its own [feature detections](https://github.com/Modernizr/Modernizr/tree/master/feature-detects)). Just like the offical detects, the result
   * will be added onto the Modernizr object, as well as an appropriate className set on
   * the html element when configured to do so
   *
   * @memberof Modernizr
   * @name Modernizr.addTest
   * @optionName Modernizr.addTest()
   * @optionProp addTest
   * @access public
   * @function addTest
   * @param {string|object} feature - The string name of the feature detect, or an
   * object of feature detect names and test
   * @param {function|boolean} test - Function returning true if feature is supported,
   * false if not. Otherwise a boolean representing the results of a feature detection
   * @example
   *
   * The most common way of creating your own feature detects is by calling
   * `Modernizr.addTest` with a string (preferably just lowercase, without any
   * punctuation), and a function you want executed that will return a boolean result
   *
   * ```js
   * Modernizr.addTest('itsTuesday', function() {
   *  var d = new Date();
   *  return d.getDay() === 2;
   * });
   * ```
   *
   * When the above is run, it will set Modernizr.itstuesday to `true` when it is tuesday,
   * and to `false` every other day of the week. One thing to notice is that the names of
   * feature detect functions are always lowercased when added to the Modernizr object. That
   * means that `Modernizr.itsTuesday` will not exist, but `Modernizr.itstuesday` will.
   *
   *
   *  Since we only look at the returned value from any feature detection function,
   *  you do not need to actually use a function. For simple detections, just passing
   *  in a statement that will return a boolean value works just fine.
   *
   * ```js
   * Modernizr.addTest('hasJquery', 'jQuery' in window);
   * ```
   *
   * Just like before, when the above runs `Modernizr.hasjquery` will be true if
   * jQuery has been included on the page. Not using a function saves a small amount
   * of overhead for the browser, as well as making your code much more readable.
   *
   * Finally, you also have the ability to pass in an object of feature names and
   * their tests. This is handy if you want to add multiple detections in one go.
   * The keys should always be a string, and the value can be either a boolean or
   * function that returns a boolean.
   *
   * ```js
   * var detects = {
   *  'hasjquery': 'jQuery' in window,
   *  'itstuesday': function() {
   *    var d = new Date();
   *    return d.getDay() === 2;
   *  }
   * }
   *
   * Modernizr.addTest(detects);
   * ```
   *
   * There is really no difference between the first methods and this one, it is
   * just a convenience to let you write more readable code.

   * @returns {string|false} The string representing the (possibly prefixed) valid
   * version of the property, or `false` when it is unsupported.
   * @example
   *
   * Modernizr.prefixed takes a string css value in the DOM style camelCase (as
   * opposed to the css style kebab-case) form and returns the (possibly prefixed)
   * version of that property that the browser actually supports.
   *
   * For example, in older Firefox...
   * ```js
   * prefixed('boxSizing')
   * ```
   * returns 'MozBoxSizing'
   *
   * In newer Firefox, as well as any other browser that support the unprefixed
   * version would simply return `boxSizing`. Any browser that does not support
   * the property at all, it will return `false`.
   *
   * By default, prefixed is checked against a DOM element. If you want to check
   * for a property on another object, just pass it as a second argument
   *
   * ```js
   * var rAF = prefixed('requestAnimationFrame', window);
   *
   * raf(function() {
   *  renderFunction();
   * })
   * ```
   *
   * Note that this will return _the actual function_ - not the name of the function.
   * If you need the actual name of the property, pass in `false` as a third argument
   *
   * ```js
   * var rAFProp = prefixed('requestAnimationFrame', window, false);
   *
   * rafProp === 'WebkitRequestAnimationFrame' // in older webkit
   * ```
   *
   * One common use case for prefixed is if you're trying to determine which transition
   * end event to bind to, you might do something like...
   * ```js
   * var transEndEventNames = {
   *     'WebkitTransition' : 'webkitTransitionEnd', * Saf 6, Android Browser
   *     'MozTransition'    : 'transitionend',       * only for FF < 15
   *     'transition'       : 'transitionend'        * IE10, Opera, Chrome, FF 15+, Saf 7+
   * };
   *
   * var transEndEventName = transEndEventNames[ Modernizr.prefixed('transition') ];
   * ```
   *
   * If you want a similar lookup, but in kebab-case, you can use [prefixedCSS](#modernizr-prefixedcss).

   * @memberof Modernizr
   * @name Modernizr.testStyles
   * @optionName Modernizr.testStyles()
   * @optionProp testStyles
   * @access public
   * @function testStyles
   * @param {string} rule - String representing a css rule
   * @param {function} callback - A function that is used to test the injected element
   * @param {number} [nodes] - An integer representing the number of additional nodes you want injected
   * @param {string[]} [testnames] - An array of strings that are used as ids for the additional nodes
   * @returns {boolean}
   * @example
   *
   * `Modernizr.testStyles` takes a CSS rule and injects it onto the current page
   * along with (possibly multiple) DOM elements. This lets you check for features
   * that can not be detected by simply checking the [IDL](https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Interface_development_guide/IDL_interface_rules).
   *
   * ```js
   * Modernizr.testStyles('#modernizr { width: 9px; color: papayawhip; }', function(elem, rule) {
   *   // elem is the first DOM node in the page (by default #modernizr)
   *   // rule is the first argument you supplied - the CSS rule in string form
   *
   *   addTest('widthworks', elem.style.width === '9px')
   * });
   * ```
   *
   * If your test requires multiple nodes, you can include a third argument
   * indicating how many additional div elements to include on the page. The
   * additional nodes are injected as children of the `elem` that is returned as
   * the first argument to the callback.
   *
   * ```js
   * Modernizr.testStyles('#modernizr {width: 1px}; #modernizr2 {width: 2px}', function(elem) {
   *   document.getElementById('modernizr').style.width === '1px'; // true
   *   document.getElementById('modernizr2').style.width === '2px'; // true
   *   elem.firstChild === document.getElementById('modernizr2'); // true
   * }, 1);
   * ```
   *
   * 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
   * them as the fourth argument, as an array of strings
   *
   * ```js
   * Modernizr.testStyles('#foo {width: 10px}; #bar {height: 20px}', function(elem) {
   *   elem.firstChild === document.getElementById('foo'); // true
   *   elem.lastChild === document.getElementById('bar'); // true
   * }, 2, ['foo', 'bar']);
   * ```
