 //	Implementation Summary
 //
 //	1. Enforce API surface and semantic compatibility with 1.9.x branch
 //	2. Improve the module's maintainability by reducing the storage
 //		paths to a single mechanism.
 //	3. Use the same single mechanism to support "private" and "user" data.
 //	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
 //	5. Avoid exposing implementation details on user objects (eg. expando properties)
 //	6. Provide a clear path for implementation upgrade to WeakMap in 2014

 // Register as a named AMD module, since jQuery can be concatenated with other

 // derived from file names, and jQuery is normally delivered in a lowercase
 // file name. Do this after creating the global so that if an AMD module wants
 // to call noConflict to hide this version of jQuery, it will work.
 
 // Note that for maximum portability, libraries that are not jQuery should
 // declare themselves as anonymous modules, and avoid setting a global if an
 // AMD loader is present. jQuery is a special case. For more information, see
 // https://github.com/jrburke/requirejs/wiki/Updating-existing-libraries#wiki-anon
