Quiz 10, 11/1

As discussed in the Lab 10 document, the myListGraph class can be easily modified to represent edge-weighted graphs by using the EdgeLinkList class to represent neighbors. Here is the beginnings of the myWeightedGraph class. The only difference between the data members of this class and the data members of the myListGraph class is that we use
			protected EdgeLinkList[] Edges;
to define the adjacency list.

Complete the two methods addEdge and getWeight, whose code is missing.
