[Lemon-devel] Renaming basic classes

Hi,

I probably lost the track, but why not Graph and DiGraph? Is there eny
problem with it?

The notation Bigraph seems also problematic, as 'Bidirected graph' is
frequently used in graph theory for something really different.

I miss the directed/undirected version of the bipartite graphs.

Peter suggested NodeA, NodeB instead. What is your opinion?
In 3G/UMTS terminology nodeB has a very special meaning. I don't know if
it is a problem.

I really don't like this. The word 'either' has a different meaning in
English. Why is this choice better than first()/second() ?

I would like to competely get rid of the word anode/bnode (and ugraph,
uedge etc. for the same reason). If it is not possible, and we continue
using the ANode as a class name, then anode() isn't so bad either.
