// CShape

// Note: this class really should be divided into a
// hierarchy with a "CShape" abstract base class and
// several derived classes "CCircle", "CSquare", etc.
//
// However, the following "everything-in-one-class"
// implementation is easier to understand and very
// straightfoward, given the limited scope of this
// sample project.
