/**
* Stub for GWT environments.
*
* Stubs are used to 'stub out' what Metawidget would normally create - either to suppress widget
* creation entirely or to create child widgets with a different name. They differ from Facets in
* that Facets are simply 'decorations' (such as button bars) to be recognized and arranged at the
* discretion of the Layout.
