How can I delegate any unrecognized method or option to a component object?
It may happen that a Snit object gets most of its behavior from one of its components. This often happens with snit::widgetadaptors, for example, where we wish to slightly the modify the behavior of an existing widget. To carry on with our dog example, however, suppose that we have a snit::type called animal that implements a variety of animal behaviors–moving, eating, sleeping, and so forth. We want our dog objects to inherit these same behaviors, while adding dog-like behaviors of its own.
