The turnLeft and turnRight methods change the direction but not the location. The move method moves the robot by one unit in the direction it is facing. The get Direction method returns a string "N", "E", "S", or "W. The default constructor must set the location to x=0 y=0 and direction to N. The toString method returns the current location and direction X Y D. Test the class by creating a Robot, have it travel around a 2x2 square, calling toString at each corner, including the initial corner.
