/** Instantiating this class will create a robot and a remote control panel to
 * control it. Use this to walk through a proposed solution to a problem. 
 * You can instantiate more than one of these to get robots with distinct
 * controllers. You can create one (or more) of these in a program that has 
 * other robots moving under program control. The response time of the 
 * controller is determined by the delay set in the world. To get the fastest
 * response, use World.setDelay(1). If you click the close control of the 
 * controller's window, the window will be made invisible, but can be 
 * brought back under program control by setting it visible again. 
 * <p> The background color of the controller is the same as the color of the
 * robot's badge (or white if none), and the controllers are assigned numbers
 * that are consistent with the robot's ID numbers (only) if these robots are
 * created before any others in your program.
