Bug Description
Following Page & Brin original paper, SocNetV computes pagerank using the formula:
PR(u1)= 1 - d + d ( PR(v1)/L(v1) + PR(v2)/L(v2) + ... ) where { v1, v2 ... } are nodes which link to u1.
This yields scores multiplied by N and the sum of all pageranks becomes N, while it should end up to be 1.
Furthermore, the initial score of each node is set to 1-d while it should be 1/N
