/**

* Grid Display Package:<br>
|
|
*
|
|
* The <code>GridObjectDisplay</code> interface contains the
|
|
* method needed to display an object in a grid.
|
|
* Objects that implement the <code>GridObjectDisplay</code>
|
|
* interface are called on by the <code>GridDisplay</code> to
|
|
* draw grid objects. The association between a
|
|
* particular <code>GridObject</code> subclass and its display
|
|
* is handled in the <code>DisplayMap</code> class.
|
|
*
|
|
* <p>
|
|
* The <code>GridObjectDisplay</code> class is based on the
|
|
* College Board's <code>LocatableDisplay</code> class,
