The YUI Global

    Provides core YUI functionality, including module registration and consumption utils,

    language/array/object utilities, browser detection, a setTimout/setInterval wrapper,

    and dynamic loading of script and css files.

    The yui module is a rollup of the following modules:

        yui-base

        get

3.0.0

* Extracted the loader from the seed file.  Instead, if loader not included, 'get' is included,

  and dependencies are missing, the loader will be fetched before continuing.

* User agent detection is more granular.  e.g., FireFox 3.5 reports gecko 1.91 rather than 1.9.

* Fixed UA.os.

* Added additional mobile device detection.

* Get utility attribute cleanup before purging nodes.

* cached accepts a parameter to refresh a cached value.

* yui-log and yui-later are now optional modules that are included with yui.js.

* queue-base is no longer a submodule of queue -- it is part of yui-base.

* All YUI submodules end up in the yui build directory.

* Dynamic loading can be disabled by setting the 'bootstrap' config to false.

3.0.0 beta 1

    Core:

    - Y.fail has been renamed to Y.error so that Y.fail can be used for the assertion

      engine.

    - Y.stamp now accepts a readOnly parameter to be used when you are only interested

      in reading an existing guid rather than creating a new one.

    - Y.stamp defends against stamping items that can't be stamped.

    - Added to Object: values(), hasKey(), hasValue(), size(), getValue, setValue

      (the latter are for manipulating nested values)

    - Y.use calls are queued during dynamic loading.

    - Added Y.cached for function memoizing

    - added numericSort to Array

    - The yui:log event broadcasts globally.

    Get:

    - Accepts an attribute collection config to apply to inserted nodes.
