+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

+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

+@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.
