Subject: Test3 on line

I have placed two sample problems on line (there is a link from "whats
new" on course web). Please take a look. Both problems require you to
complete class methods and test them out in main. I will add more problems
later.

Lab6 Hint: In order to change a vector element you can use:
setElementAt(Object obj, int index)
          Sets the component at the specified index of this vector to be
the specified object.

from the vector class. For example to insert a Edge to the front.
1. create a new edge
2. Link this to current first
3. using setElementAt  make the first entry of the vector to new edge
