Define a class named randomwalker. a randomwalker object should keep track of its (x, y) location. all walkers start at the coordinates (0, 0). when a walker is asked to move, it randomly moves either left, right, up or down. each of these four moves should occur with equal probability. the resulting behavior is known as a "random walk." (a 2-dimensional random walk example is pictured at right.) each randomwalker object should have the following public methods. you may add whatever fields or methods you feel are necessary to implement these methods: move() instructs this random walker to randomly make one of the 4 possible moves (up, down, left, or right). getx() returns this random walker's current x-coordinate.
