//	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)

// 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
