/**
The YUI global namespace object. This is the constructor for all YUI instances.

This is a self-instantiable factory function, meaning you don't need to precede
it with the `new` operator. You can invoke it directly like this:

    YUI().use('*', function (Y) {
        // Y is a new YUI instance.
    });

But it also works like this:

    var Y = YUI();

The `YUI` constructor accepts an optional config object, like this:

    YUI({
        debug: true,
        combine: false
    }).use('node', function (Y) {
        // Y.Node is ready to use.
    });

See the API docs for the <a href="config.html">Config</a> class for the complete
list of supported configuration properties accepted by the YUI constuctor.

If a global `YUI` object is already defined, the existing YUI object will not be
overwritten, to ensure that defined namespaces are preserved.

Each YUI instance has full custom event support, but only if the event system is
available.

@class YUI
@uses EventTarget
@constructor
@global
@param {Object} [config]* Zero or more optional configuration objects. Config
    values are stored in the `Y.config` property. See the
    <a href="config.html">Config</a> docs for the list of supported properties.

/**
Registers a YUI module and makes it available for use in a `YUI().use()` call or
as a dependency for other modules.

The easiest way to create a first-class YUI module is to use
<a href="http://yui.github.com/shifter/">Shifter</a>, the YUI component build
tool.

Shifter will automatically wrap your module code in a `YUI.add()` call along
with any configuration info required for the module.

@example

    YUI.add('davglass', function (Y) {
        Y.davglass = function () {
            Y.log('Dav was here!');
        };
    }, '3.4.0', {
        requires: ['harley-davidson', 'mt-dew']
    });

@method add
@param {String} name Module name.
@param {Function} fn Function containing module code. This function will be
    executed whenever the module is attached to a specific YUI instance.

    @param {YUI} fn.Y The YUI instance to which this module is attached.
    @param {String} fn.name Name of the module

@param {String} version Module version number. This is currently used only for
    informational purposes, and is not used internally by YUI.

@param {Object} [details] Module config.
    @param {Array} [details.requires] Array of other module names that must be
        attached before this module can be attached.
    @param {Array} [details.optional] Array of optional module names that should
        be attached before this module is attached if they've already been
        loaded. If the `loadOptional` YUI option is `true`, optional modules
        that have not yet been loaded will be loaded just as if they were hard
        requirements.
    @param {Array} [details.use] Array of module names that are included within
        or otherwise provided by this module, and which should be attached
        automatically when this module is attached. This makes it possible to
        create "virtual rollup" modules that simply attach a collection of other
        modules or submodules.

@return {YUI} This YUI instance.

      * All required modules have already been loaded, and just need to be

        be executed synchronously after the modules are attached.

      * One or more modules have not yet been loaded, or the Get utility is not
        available, or the `bootstrap` config option is `false`. In this case,
        a warning is issued indicating that modules are missing, but all
        available modules will still be attached and the `use()` callback will
        be executed synchronously.

      * One or more modules are missing and the Loader is not available but the
        Get utility is, and `bootstrap` is not `false`. In this case, the Get
        utility will be used to load the Loader, and we will then proceed to
        the following state:

      * One or more modules are missing and the Loader is available. In this
        case, the Loader will be used to resolve the dependency tree for the
        missing modules and load them and their dependencies. When the Loader is
        finished loading modules, the `use()` callback will be executed
        asynchronously.

    @example

        // Loads and attaches dd and its dependencies.
        YUI().use('dd', function (Y) {
            // ...

        // Attaches all modules that have already been loaded.

    /**
    Utility method for safely creating namespaces if they don't already exist.
    May be called statically on the YUI global object or as a method on a YUI
    instance.

    When called statically, a namespace will be created on the YUI global
    object:

        // Create `YUI.your.namespace.here` as nested objects, preserving any
        // objects that already exist instead of overwriting them.
        YUI.namespace('your.namespace.here');

    When called as a method on a YUI instance, a namespace will be created on
    that instance:

        // Creates `Y.property.package`.
        Y.namespace('property.package');

    Dots in the input string cause `namespace` to create nested objects for each
    token. If any part of the requested namespace already exists, the current
    object will be left in place and will not be overwritten. This allows
    multiple calls to `namespace` to preserve existing namespaced properties.

    If the first token in the namespace string is "YAHOO", that token is
    discarded. This is legacy behavior for backwards compatibility with YUI 2.

    Be careful with namespace tokens. Reserved words may work in some browsers
    and not others. For instance, the following will fail in some browsers
    because the supported version of JavaScript reserves the word "long":

        Y.namespace('really.long.nested.namespace');

    Note: If you pass multiple arguments to create multiple namespaces, only the
    last one created is returned from this function.

    @param {String} namespace* One or more namespaces to create.
    @return {Object} Reference to the last namespace object created.

This isn't guaranteed to be 100% accurate and won't work for anything other than
functions, but it can be useful for determining whether a function like
`Array.prototype.forEach` is native or a JS shim provided by another library.

There's a great article by @kangax discussing certain flaws with this technique:
<http://perfectionkills.com/detecting-built-in-host-methods/>

While his points are valid, it's still possible to benefit from this function
as long as it's used carefully and sparingly, and in such a way that false
negatives have minimal consequences. It's used internally to avoid using
potentially broken non-native ES5 shims that have been added to the page by
other libraries.

/**
Performs a simple comparison between two version numbers, accounting for
standard versioning logic such as the fact that "535.8" is a lower version than
"535.24", even though a simple numerical comparison would indicate that it's
greater. Also accounts for cases such as "1.1" vs. "1.1.0", which are
considered equivalent.

Returns -1 if version _a_ is lower than version _b_, 0 if they're equivalent,
1 if _a_ is higher than _b_.

Versions may be numbers or strings containing numbers and dots. For example,
both `535` and `"535.8.10"` are acceptable. A version string containing
non-numeric characters, like `"535.8.beta"`, may produce unexpected results.

@method compareVersions
@param {Number|String} a First version number to compare.
@param {Number|String} b Second version number to compare.
@return -1 if _a_ is lower than _b_, 0 if they're equivalent, 1 if _a_ is

    Default options to use for all requests.

    Note that while all available options are documented here for ease of
    discovery, some options (like callback functions) only make sense at the
    transaction level.

    Callback functions specified via the options object or the `options`
    parameter of the `css()`, `js()`, or `load()` methods will receive the
    transaction object as a parameter. See `Y.Get.Transaction` for details on
    the properties and methods available on transactions.

    @static
    @since 3.5.0
    @property {Object} options

    @property {Boolean} [options.async=false] Whether or not to load scripts
        asynchronously, meaning they're requested in parallel and execution
        order is not guaranteed. Has no effect on CSS, since CSS is always
        loaded asynchronously.

    @property {Object} [options.attributes] HTML attribute name/value pairs that
        should be added to inserted nodes. By default, the `charset` attribute
        will be set to "utf-8" and nodes will be given an auto-generated `id`
        attribute, but you can override these with your own values if desired.

    @property {Boolean} [options.autopurge] Whether or not to automatically
        purge inserted nodes after the purge threshold is reached. This is
        `true` by default for JavaScript, but `false` for CSS since purging a
        CSS node will also remove any styling applied by the referenced file.

    @property {Object} [options.context] `this` object to use when calling
        callback functions. Defaults to the transaction object.

    @property {Mixed} [options.data] Arbitrary data object to pass to "on*"
        callbacks.

    @property {Document} [options.doc] Document into which nodes should be
        inserted. By default, the current document is used.

    @property {HTMLElement|String} [options.insertBefore] HTML element or id
        string of an element before which all generated nodes should be
        inserted. If not specified, Get will automatically determine the best
        place to insert nodes for maximum compatibility.

    @property {Function} [options.onEnd] Callback to execute after a transaction
        is complete, regardless of whether it succeeded or failed.

    @property {Function} [options.onFailure] Callback to execute after a
        transaction fails, times out, or is aborted.

    @property {Function} [options.onProgress] Callback to execute after each
        individual request in a transaction either succeeds or fails.

    @property {Function} [options.onSuccess] Callback to execute after a
        transaction completes successfully with no errors. Note that in browsers
        that don't support the `error` event on CSS `<link>` nodes, a failed CSS
        request may still be reported as a success because in these browsers
        it can be difficult or impossible to distinguish between success and
        failure for CSS resources.

    @property {Function} [options.onTimeout] Callback to execute after a
        transaction times out.

    @property {Number} [options.pollInterval=50] Polling interval (in
        milliseconds) for detecting CSS load completion in browsers that don't
        support the `load` event on `<link>` nodes. This isn't used for
        JavaScript.

    @property {Number} [options.purgethreshold=20] Number of nodes to insert
        before triggering an automatic purge when `autopurge` is `true`.

    @property {Number} [options.timeout] Number of milliseconds to wait before
        aborting a transaction. When a timeout occurs, the `onTimeout` callback
        is called, followed by `onFailure` and finally `onEnd`. By default,
        there is no timeout.

    @property {String} [options.type] Resource type ("css" or "js"). This option
        is set automatically by the `css()` and `js()` functions and will be
        ignored there, but may be useful when using the `load()` function. If
        not specified, the type will be inferred from the URL, defaulting to
        "js" if the URL doesn't contain a recognizable file extension.

    Loads one or more CSS and/or JavaScript resources in the same transaction.

    Use this method when you want to load both CSS and JavaScript in a single
    transaction and be notified when all requested URLs have finished loading,

    Behavior and options are the same as for the `css()` and `js()` methods. If
    a resource type isn't specified in per-request options or transaction-level
    options, Get will guess the file type based on the URL's extension (`.css`

    be guessed from the URL, a warning will be logged and Get will assume the
    URL is a JavaScript resource.
