[igraph] size vs order

[John Lapeyre]

Hello,

In igraph, is there a consistent use of words for |V| and |E|?
In mathematics the words are 'order' for |V| and 'size' for |E|.
In igraph, it seems like 'size' is for |V| while |E| is simply called
something like number of edges. I know its a lot of work, but a small
glossary of definitions might help clarify things, ie, in this case
"the size of G  means |V(G)|".

Eg the description of  igraph_clusters has
  ... For every component it gives its size ...

Regards,
John
