No messing around with strcat() here...  // Left as an exercise: Modify this so that it will look at the "neighbours"  // vector and add information about what directions are valid.  // You may find you want to associate a name with each "direction". Of course,  // you can't just add a "direction" string to each Room, because you could  // enter a room in several ways. The name needs to be associated with the  // link itself.  // Fortunately the standard library provides a cheap hack for handling simple  // pairings like this: look up std::pair.

All Rooms should behave in the same  // fundamental way; that's part of the abstraction.  // 4) Try to do some arithmetic on the choice in order to get an array index.  // 5) Return NULL to indicate that the user has exited and is in "no room".}
