4161//	1. Enforce API surface and semantic compatibility with 1.9.x branch
4162//	2. Improve the module's maintainability by reducing the storage
4163//		paths to a single mechanism.
4164//	3. Use the same single mechanism to support "private" and "user" data.
4165//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
4166//	5. Avoid exposing implementation details on user objects (eg. expando properties)
4167//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

10371// way to register. Lowercase jquery is used because AMD module names are
10372// derived from file names, and jQuery is normally delivered in a lowercase
10373// file name. Do this after creating the global so that if an AMD module wants
10374// to call noConflict to hide this version of jQuery, it will work.
10375
10376// Note that for maximum portability, libraries that are not jQuery should
10377// declare themselves as anonymous modules, and avoid setting a global if an
10378// AMD loader is present. jQuery is a special case. For more information, see
