Makes sense.  We always start with the "need to know" principle; in this 
case exposing it as public seems like the right thing to do.  I'll 
change it for 0.7.1.

I suppose the subclasses need covariant accessor methods; e.g. 
UndirectedSubgraph should override getBase() to return an 
UndirectedGraph.  Luckily that's now possible in Java 1.5.  (We'll see 
what retroweaver makes of it.)
