Example data for BlockchainBench.

- configuration.json: the base configuration every simulation group shares
  (Monte-Carlo, blockchain length 60).
- optimized_deterministic_lhs_configurations.csv: five example simulation
  configurations; each row resolves its model from testmodels/threesim-<id>.
- testmodels/: the example blockchain system models.

The application resolves this folder relative to its working directory -
start it through the provided start script, which takes care of that.
