The Pagerank package provides a single driver call capable of
running different pagerank algorithm.
1) PageRank with power iterations
2) PageRank with gauss-seidel iterations
3) PageRank as a linear system (bicgstab and
gmres solvers)
4) PageRank with the arnoldi factorization
5) Approximate personalized PageRank
