public interface GridObjectDisplay

Grid Display Package:
The GridObjectDisplay interface contains the method needed to display an object in a grid. Objects that implement the GridObjectDisplay interface are called on by the GridDisplay to draw grid objects. The association between a particular GridObject subclass and its display is handled in the DisplayMap class.

The GridObjectDisplay class is based on the College Board's LocatableDisplay class, as allowed by the GNU General Public License.
