/**
* Neighborhood (OOP Example)
* By Ira Greenberg
*
* Draw a neighborhood of houses using
* Door, Window, Roof and House classes.
* Good example of class composition, with component
* Door, Window, Roof class references encapsulated
* within House class. This arrangement allows
* House class to handle placement and sizing of
* its components, while still allowing user
* customization of the individual components.
