//      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

// understands anonymous AMD modules. A named AMD is safest and most robust
// way to register. Lowercase jquery is used because AMD module names are
// 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
