Write an instruction followWallRight for the MazeWalker class, assuming that whenever a robot executes this instruction there is a wall directly to the right.

Here are four of the different position changes that the robot must be able to make. This instruction is the cornerstone for a program that directs a robot to escape from a maze (for homework later)
