> Original assumptions in Giraph were that all users would subclass Vertex (which extended
MutableVertex extended BasicVertex).  Classes which wish to have application specific data
structures (ie. not a TreeMap<I, Edge<I,E>>) may need to extend either MutableVertex
or BasicVertex.  Unfortunately VertexRange extends ArrayList<Vertex>, and there are
other places where the assumption is that vertex classes are either Vertex, or at least MutableVertex.
> Let's make sure the internal APIs allow for BasicVertex to be the base class.
