General Template for Lab 4 Grading: 

Operation               : 50/50
Design & Documentation  : 20/20 
Format                  : 15/15
Report                  : 15/15
 
Total                   : 100/100
Of course since there are a number of operations to implement, 
  (C)onnected()  
  (B)iConnected()
  (A)rticulations()
  (M)inCostSpanTree()
  (S)SShortestPath
each one not working will reduce the points for Operation by 10 points.
