@iyerr3 @orhankislal All the `*_for_centrality_measures` functions are
currently only used in `pagerank` and `hits`, which are centrality measures.
They can potentially be used in future centrality measure modules, hence the
generic name and not something like `*hits_pagerank*`.
Any suggestions on what is a better naming convention?---
