Add a personalization vector option for personalized pagerank?

[ddu1]

Maybe I missed it in the documentation, but I couldn't find an option to pass in a non-evenly-distributed personalization vector to the ppr algorithm, other than a list of sourceNodes (which implies evenly-distributed?) :

https://github.com/neo4j-contrib/neo4j-graph-algorithms/blob/3.4.7.0/algo/src/main/java/org/neo4j/graphalgo/PageRankProc.java#L196

It would be a very nice feature to have, similar to what is implemented here.

I agree. I believe this is already discussed in #271 , where I suggest passing a named reference to a probability property on the nodes.
