* addTest allows you to define your own feature detects that are not currently
* included in Modernizr (under the covers it's the exact same code Modernizr
* 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.

* @param {string} rule - String representing a css rule

* @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']);
