====== Newspaper Retrieval ======
Every morning Karel is awakened in bed when the newspaper, represented by a beeper, is thrown on the front porch of his house. Program Karel to retrieve the paper  and bring it back to bed. Karel is inside in the southwest corner (Street 3, Avenue 4), while the newspaper is outside on the other side of the wall (Street 3, Avenue 3)  Below is the description of the world:
