Add Pagerank

[newmanrs]

If graph data library (GDS) is installed,

CALL gds.graph.create.cypher(
    'full_graph',
    'MATCH (n) RETURN id(n) AS id',
    'MATCH (n)-[e]-(m) RETURN id(n) AS source, e.weight AS weight, id(m) AS target'
)

CALL gds.pageRank.write('full_graph', {
    maxIterations: 200,
    dampingFactor: 0.85,
    writeProperty: 'full_pagerank'})

Results of above queries pass the plausibility test of the most central Hops at Cloudburst being by far Citra (see attachment)

• Add these steps to ETL script
• Add exception handling to pass if GDS is missing.
