    a no-op class, for systems which do not use the UIBuilder.

    Concrete subclasses know how to create a view (with components) from

    some interface spec. Currently, an experimantal version of UIBuilder exists,

    and more may be added in the future (for example, to parse different UI

    specs - thinking of motifs UIL specs etc).
