 * @class Loader

 * @param {Object} config an optional set of configuration options.

 * @param {String} config.base The base dir which to fetch this module from

 * @param {String} config.comboBase The Combo service base path. Ex: `http://yui.yahooapis.com/combo?`

 * @param {String} config.root The root path to prepend to module names for the combo service. Ex: `2.5.2/build/`

 * @param {String|Object} config.filter A filter to apply to result urls. <a href="#property_filter">See filter property</a>

 * @param {Object} config.filters Per-component filter specification.  If specified for a given component, this overrides the filter config.

 * @param {Boolean} config.combine Use a combo service to reduce the number of http connections required to load your dependencies

 * @param {Boolean} [config.async=true] Fetch files in async

 * @param {Array} config.ignore: A list of modules that should never be dynamically loaded

 * @param {Array} config.force A list of modules that should always be loaded when required, even if already present on the page

 * @param {HTMLElement|String} config.insertBefore Node or id for a node that should be used as the insertion point for new nodes

 * @param {Object} config.jsAttributes Object literal containing attributes to add to script nodes

 * @param {Object} config.cssAttributes Object literal containing attributes to add to link nodes

 * @param {Number} config.timeout The number of milliseconds before a timeout occurs when dynamically loading nodes.  If not set, there is no timeout

 * @param {Object} config.context Execution context for all callbacks

 * @param {Function} config.onSuccess Callback for the 'success' event

 * @param {Function} config.onFailure Callback for the 'failure' event

 * @param {Function} config.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.

 * @param {Function} config.onTimeout Callback for the 'timeout' event

 * @param {Function} config.onProgress Callback executed each time a script or css file is loaded

 * @param {Object} config.modules A list of module definitions.  See <a href="#method_addModule">Loader.addModule</a> for the supported module metadata

 * @param {Object} config.groups A list of group definitions.  Each group can contain specific definitions for `base`, `comboBase`, `combine`, and accepts a list of `modules`.

 * @param {String} config.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.

 * @param {String} config.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`, `2.8.1` and `2.9.0` [default] -- plus all versions of YUI 2 going forward.
