 * This is a subclass of RectangleCity, which is a subclass of becker.City.

 * This class creates a completely fenced in yard with a house

 * The house sits on the back of the lot - joining the back fence.
 * There is a single door in the front of the house facing south.
 *
 * There are a number of dandelions in the west yard - none in front or the
 * 	in the east yard - there is no back yard.
 * The northwest corner of the yard is always (1, 1).
 *
 * There are are a number of constants created to setup the elements.
 * Their values may be changed to vary the yard layout.
