I took your advice and checked by trying something (e.g. a star graph) in
both R and Python. The defaults are different for each version of igraph.
It appears that in python the closeness has default normalized=TRUE ,
while betweenness has default normalized=FALSE. In R, the defaults are
both normalized=FALSE.
