Benchmarking and optimisation

[matentzn]

• I think the most promising spot for optimisation is Extracting annotations to literals. Other things:
• Right now the ontology is loaded over the network - that is what makes this step particularly slow. But on module level there is nothing to optimise.
• The second most promising spot is the import of the CSVs - 40 min seems a lot for relatively little data (in neo4j terms).. But to be honest, the best I could probably squeeze out is 20 min - and that would take a lot of work..

I think current efficiency is good enough. Moving to icebox rather than closing - just in case we need to revisit in future.
