 *
 * 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.
 *
 * @class Loader
 * @constructor
 * @param 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: &#123; 
 *      'searchExp': "-min\\.js", 
 *      'replaceStr': "-debug.js"
 *  &#125;

 *

 *  <li>filters: per-component filter specification.  If specified for a given component, this overrides the filter config</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>
