Parallelisation

[AugustT]

Given that the world building is an 'embarrassingly parallel' problem there could be some big speed gains here. We should look into multi-core solutions in python, no idea how easy/hard these are. We could then in theory upscale to JASMIN if we wanted to 'go big'.

If we are ever going to go big we need to figure this one out. I think there is an answer in here somewhere
