Modifying Existing Figures
The framework comes presupplied with many different types of Figure.
Often developers will find that predefined figures deliver only part of
the functionality required for their application. In such circumstances
figures can be subclassed to defined the required behaviour.
It is important to develop a good understanding of a Figures behaviour
before subclassing to identify which methods will have to be overriden
and what extra methods will have to be added to create the new figure.
When creating a new subclass remember to maintain the naming convention
of ending the class name with Figure.
