/**
 * Title:       TestRobot class
 * Description: Contains test code for various types of robot objects
 *              Creates robot objects of various types and invokes some
 *              of their methods.  Displays the results both as text output
 *              and graphically on a display grid in 'slow motion'.
 *              At this stage, you are not expected to understand how the
 *              display grid works - it is purely for demonstration.
 *
 *              This class is complete and you should not need to change it
