[igraph] Another fast community detection algorithm

[Gang Su]

Dear Developers,

I have been using another fast community detection algorithm. It 
produces more balanced clusters than the fast-greedy one.

They have a java implementation, i don't know how difficult is it to be 
implemented in R.
Java function is here.

Hope it helps
