Good point... actually I realized that Ben earlier suggested we use  
these categories:

c("all","tips","internal","edges") {where "all"= "tips+internal"}.

I can update labels, tdata, and so on to use the new terminology, we  
will have to change the names and documentation for some of the  
methods (nNodes, hasNodeLabels, etc.) as well.

Are there any more decisions to be made about what to call things?
Tips, internals, nodes, edges
Descendant, ancestor, sister
?
