Added a "fork me" ribbon and made border radius more subtle across the site.
Switched to `class` (using backticks) instead of $class$ for namespaced class names.
Removed some private instance methods from polluting the instance properties by making them truly private, and gave the size state property an initial value.
Don't need this console.log here.
This actually now needs to be a V2 widget because of the template.
Lightened page colors for the UIZE Web site.
Added support for extra classes that are stitched in every time the class string is computed for the root node of a V2 widget.
Added new onChange and whenever instance methods.
Factored out the progress bar code from the UIZE Unit Tests page into a new V2 widget.
