//  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

// Note that for maximum portability, libraries that are not jQuery should
