Lab 4: Coursework
    
       - Formative Assesment of Coursework 1. 
 
       - If you haven't started yet, read the data in. 
 
       - Once you've got that, try a best first search. 
 
       - After that, try an exhaustive algorithm like depth or breadth first.
 
       - Then Dijkstra's. 
 
       - Then something clever. 
 
       - Of course, you're free to select any algorithm you like to explore. 
 
       - Come to the lab, Chris will look at, and comment on your coursework.
           (I may even help with some simple debugging.)
