(abstract base class)
Description
This abstract base class has been designed to implement the "Model" leg of a
Model-View-Controller architecture. A companion class, RWModelClient, supplies the "View"
leg.
It maintains a list of dependent RWModelClient objects. When member function
changed(void*) is called, the list of dependents will be traversed, calling
updateFrom(RWModel*, void*) for each one, with itself as the first argument. Subclasses of
RWModelClient should be prepared to accept such a call.

classes involved. "Dial" is assumed to be a graphical representation of the internal settings of
"Thermostat." The essential point is that there is a dependency relationship between the
