When updating a node's authority score using the hub scores of each node
that points to it, the hub scores are multiplied by the weights of the
incoming edges. That is, a node is given a higher authority if it is
being linked to by pages with high hub scores and those links have a
high weight. The hub update rule is modified similarly. When all weights
are equal, the algorithm becomes equivalent to the unweighted case.
