* Loader dynamically loads script and css files. It includes the dependency
* info for the version of the library in use, and will automatically pull in

* files from the Yahoo! CDN, and it can utilize the combo service provided on
* this network to reduce the number of http connections required to download
* YUI files.
*
* While the loader can be instantiated by the end user, it normally is not.
* @see YUI.use for the normal use case. The use function automatically will
* pull in missing dependencies.
*
* @constructor
* @class Loader
* @param {object} o an optional set of configuration options. Valid options:
* <ul>
* <li>base:
* The base dir</li>
* <li>comboBase:
* The YUI combo service base dir. Ex: http://yui.yahooapis.com/combo?</li>
* <li>root:
* The root path to prepend to module names for the combo service.
* Ex: 2.5.2/build/</li>
* <li>filter:.
*
* A filter to apply to result urls. This filter will modify the default
* path for all modules. The default path for the YUI library is the
* minified version of the files (e.g., event-min.js). The filter property
* can be a predefined filter or a custom filter. The valid predefined
* filters are:
* <dl>
* <dt>DEBUG</dt>
* <dd>Selects the debug versions of the library (e.g., event-debug.js).
* This option will automatically include the Logger widget</dd>
* <dt>RAW</dt>
* <dd>Selects the non-minified version of the library (e.g., event.js).
* </dd>
* </dl>
* You can also define a custom filter, which must be an object literal
* containing a search expression and a replace string:
* <pre>
* myFilter: {
* 'searchExp': "-min\\.js",
* 'replaceStr': "-debug.js"
* }
* </pre>
*
* </li>
* <li>filters: per-component filter specification. If specified
* for a given component, this overrides the filter config. _Note:_ This does not work on combo urls, use the filter property instead.</li>
* <li>combine:
* Use the YUI combo service to reduce the number of http connections
* required to load your dependencies</li>
* <li>ignore:
* A list of modules that should never be dynamically loaded</li>
* <li>force:
* A list of modules that should always be loaded when required, even if
* already present on the page</li>
* <li>insertBefore:
* Node or id for a node that should be used as the insertion point for
* new nodes</li>
* <li>charset:
* charset for dynamic nodes (deprecated, use jsAttributes or cssAttributes)
* </li>
* <li>jsAttributes: object literal containing attributes to add to script
* nodes</li>
* <li>cssAttributes: object literal containing attributes to add to link
* nodes</li>
* <li>timeout:
* The number of milliseconds before a timeout occurs when dynamically
* loading nodes. If not set, there is no timeout</li>
* <li>context:
* execution context for all callbacks</li>
* <li>onSuccess:
* callback for the 'success' event</li>
* <li>onFailure: callback for the 'failure' event</li>
* <li>onCSS: callback for the 'CSSComplete' event. When loading YUI
* components with CSS the CSS is loaded first, then the script. This
* provides a moment you can tie into to improve
* the presentation of the page while the script is loading.</li>
* <li>onTimeout:
* callback for the 'timeout' event</li>
* <li>onProgress:
* callback executed each time a script or css file is loaded</li>
* <li>modules:
* A list of module definitions. See Loader.addModule for the supported
* module metadata</li>
* <li>groups:
* A list of group definitions. Each group can contain specific definitions
* for base, comboBase, combine, and accepts a list of modules. See above
* for the description of these properties.</li>
* <li>2in3: the version of the YUI 2 in 3 wrapper to use. The intrinsic
* support for YUI 2 modules in YUI 3 relies on versions of the YUI 2
* components inside YUI 3 module wrappers. These wrappers
* change over time to accomodate the issues that arise from running YUI 2
* in a YUI 3 sandbox.</li>
* <li>yui2: when using the 2in3 project, you can select the version of
* YUI 2 to use. Valid values * are 2.2.2, 2.3.1, 2.4.1, 2.5.2, 2.6.0,
* 2.7.0, 2.8.0, and 2.8.1 [default] -- plus all versions of YUI 2
* going forward.</li>
