I wonder if your having a hard time because of primary keys.  That is 
maybe you should define the "edges" table like

ID
Child
Parent

Then you could use a single "Vector" class with 2 has_a's, one along the 
parent and one along the child.

Otherwise if you define the Vector table with a multi key primary key 
(MKPK), I think you'll run into a bug about having an MKPK and has_a's 
on the pk columns
