RtkDev:CoreJs

From RevTK

All the front end code is currently refactored for YUI 3.

For maximum front end code reuse between RevTK and RevTH (chinese version), all front end components are now separate files, each with their own directory and assets. Juicer is used to concatenate all javascript code and stylesheets and produce single files for the production site.

The front end components (classes, widgets, ...) need to be generic, but are clearly developed following the needs of the RevTK application.

coreJs also acts as a wrapper around the javascript library.
