AngularJS using module pattern and AMD pattern (e.g RequireJS) - Shows how the define() is encapsulated without global variable requirements - Shows how `supplant` functionality is dynamically loaded and injected as a define() MD5Factory argument. - Shows how RequireJS registers the MD5 constructor now accessible to all RequireJS subscribers usi…
