    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).
