Lab 7: Coursework
    
       - Formative Assesment of Coursework 1. 
 
       - You should have an exhaustive algorithm like depth or breadth first
	 working reading the data from a file. If not:
       
	 - 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. This should be enough to pass.
 
       
  
       - 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.)
